🔧 Component Overview

The DJI Agras T50 OEM RTK Dongle, DJI material number BC.AG.SS000774, is the module that brings RTK (real-time kinematic) correction into the aircraft, taking positioning from meter-level to centimeter-level so flight lines are tight, repeatable, and free of the drift that causes skips and overlaps.

It helps to see RTK as a chain rather than as a box. Satellites are observed by the aircraft's antennas, a correction stream arrives from either a base station or a network service, and this module is what brings the two together so the flight controller can hold a precise position. Any link in that chain can break, and only one of those links is the part on this page. Working out which link actually failed is what separates an afternoon of work from a week of guessing.

The most useful split in the field is between no fix at all and a fix that will not hold. A module that is not recognized, or that never reaches fix no matter where you set up, points at aircraft-side hardware and its connection. A fix that establishes and then drops at particular spots in a field, at particular times of day, or as the aircraft works further from the base is almost always the sky or the correction path, and a new dongle changes none of it.

⚙️ Functional Purpose

The dongle processes RTK correction data so the flight controller holds precise position. When it fails, positioning falls back to standard GNSS accuracy — the aircraft still flies, but line spacing loosens, repeatability suffers, and coverage quality drops.

Power the aircraft down and disconnect the flight batteries before touching the module or its port. Photograph how it sits, which way any keying or label faces, and how the cover or seal is fitted, because those details matter more on a sealed electronic module than they do on a structural part. Handle it by its body rather than its contacts, and keep it off a bare metal bench while you work.

The port is the fragile half of this job. Look into it under good light before anything mates: bent or recessed pins, moisture, green or white corrosion, and packed dust are all things you cannot see once the module is home, and every one of them will make a brand new dongle look faulty. Blow it out dry rather than washing it, and never force a module that does not want to seat, because the keying exists to stop the exact mistake that bends a pin.

Seat it square and fully home, then secure whatever retains it before the cover goes back on. If your installation uses a gasket, cap, or cover over the port, fit it properly and check that it compresses evenly all the way round, because this bay lives in the same spray mist and washdown water as the rest of the aircraft. A cover left loose or a seal left twisted is how the next dongle dies.

Verify on the pad, not in the field. Power up and confirm the aircraft actually recognizes the module, then confirm the correction source is connected and that status climbs to fix while parked in clear sky away from buildings and tree lines. If the app asks for a firmware update after a module change, run it on a charged battery and let it finish rather than skipping past it, and re-check that your correction source settings and any network credentials survived the swap.

⚠️ Common Replacement Indicators

• Loss of RTK / centimeter-level positioning (drops to standard GNSS)
• RTK status that will not reach FIX
• Line-to-line drift, skips, or overlaps in coverage
• RTK module not recognized or faulted in the app
• Physical, heat, or water damage to the dongle

Confirm before you order: this dongle is DJI part BC.AG.SS000774, listed for the DJI Agras T50 and T100. Match the number to your parts diagram, and confirm the fault is the dongle rather than the base station, network RTK service, or antenna.

RTK that never reaches fix anywhere is a correction-data problem far more often than it is a dead module. Work the supply side first: confirm the base station is powered, set up, and broadcasting, or that the network service is authenticated and the controller still has a live data connection. Then check the satellite count the aircraft is actually seeing. Only when correction data is proven to be arriving and the module still will not use it does the dongle become the suspect.

A fix that is solid on the pad and drops once the aircraft is working points away from the module. Look at the aircraft's RTK antennas and their cables and connectors for damage or chafe, at whether the far end of the field sits in a radio shadow from the base, and at how far the aircraft is getting from that base, since correction quality falls off with distance. A module that is genuinely failing usually misbehaves standing still as well as flying.

A module that shows as not recognized or faulted in the app is the one case that most often does come back to this part or its connection. Before ordering, pull it, inspect both sets of contacts for moisture and corrosion, reseat it firmly, and confirm the firmware is what the aircraft expects. A module that stays unrecognized after a clean, dry reseat and a firmware check has earned its replacement.

Tight lines that repeat perfectly within a day but do not line up with last season's passes are not a hardware fault at all. That is the base station's coordinate reference moving. A base set up over an unmarked spot gives excellent relative accuracy for that flight and a different absolute origin the next time it is placed, so year-over-year repeatability depends on surveying the base position or using the same network reference rather than on replacing anything on the aircraft.

📐 Specifications

DJI Material Number: BC.AG.SS000774

Part: RTK Dongle

Fits: DJI Agras T50, T100 (supplier-listed fitment)

Quantity: 1 dongle

Condition: Brand new

Published electrical figures: No voltage, current, data rate, or positioning accuracy figures are published in this listing. Work from the DJI material number and the removed part rather than from a guessed value

Correction source not included: This is the aircraft-side module only. It does not generate correction data by itself; that comes from a D-RTK base station or a network RTK service, and neither is part of this order

Firmware: A replacement module may prompt for a firmware update on first power-up. Run whatever the app requests, on a charged battery, and let it complete before the aircraft returns to work

🧰 Fitment Verification Before You Order

This listing is DJI material number BC.AG.SS000774. That number, not the description, is what makes a part match. Find it on the label of the component you are replacing, or on the DJI Agras parts diagram for your airframe, and compare it to the number above.

Revision suffixes are still the same part. DJI labels sometimes carry a trailing revision such as .01, .02, or .F. Those denote a production revision, not a different component. Match the base number and disregard the suffix.

Visually similar is not the same. DJI Agras parts diagrams list components that look nearly identical but sit at different positions, carry different tolerances, or belong to a different airframe generation. Ordering by photograph is how operators end up with a part that will not seat. Order by number.

Verified fitment for this listing: DJI Agras T50 / DJI Agras T100. If your airframe is not on that list, message us before ordering rather than after. We would rather answer a question than process a return, and so would you.

Not sure? Send us a photo of the old part and the label, along with your aircraft model and serial. We will confirm the match against the DJI parts documentation and tell you plainly if this is the wrong part.

🛠️ Installation & Handling Notes

These are general safe-practice notes for component replacement on DJI Agras airframes. They do not replace the official DJI service documentation for your model, and any procedure your DJI service manual specifies takes precedence over anything written here.

Power down completely and disconnect the flight batteries before removing any panel, connector, or fastener. Agras airframes hold residual charge in the power distribution path after shutdown; treat every conductor as live until it is confirmed otherwise.

Photograph the assembly before you disturb it. Cable routing, connector orientation, and fastener lengths on Agras airframes are not interchangeable, and the RTK Dongle is easier to fit correctly when you can see how the original sat.

Observe ESD precautions. Ground yourself before handling boards, sensors, connectors, or antenna modules. Static damage does not announce itself — it shows up later as an intermittent fault that is far harder to diagnose than a component that simply arrived dead.

Seat every connector fully and restore the original strain relief. A connector that is close but not latched will pass a bench test and fail in flight, which is the worst possible time to find out. Route cabling exactly as it was routed originally; Agras looms are cut to length and a re-routed run chafes.

Test before you spray. Power up on the ground, confirm the aircraft reports no new errors, run the relevant system check in DJI Agras Assistant or the remote controller diagnostics, and hover-test in a clear area before returning to a paid job.

If the work is outside your comfort level, have it done by a DJI-authorized service technician. The part cost is small next to the airframe.

🚜 Necessary For

• Restoring centimeter-level RTK positioning
• Curing RTK that will not reach FIX
• Tightening line spacing and coverage repeatability
• Replacing a dongle lost to heat, water, or connector damage

Work where the line is the product. Prescription and variable-rate application, repeat passes over the same crop through a season, and any job flown close to a sensitive neighbor, a waterway, or a boundary all depend on the aircraft putting itself exactly where the map says. Operators doing that kind of work generally keep a spare module rather than lose the precision half of their capability for the length of a shipping delay.

💵 What Downtime Actually Costs

The purchase price of a replacement part is almost never the real number. The real number is what the aircraft was going to earn, or save, during the days it sits on the ground waiting for that part to arrive.

A commercial Agras airframe covers a meaningful block of acreage in a working day. When a spray window is open — the right growth stage, the right wind, the right soil moisture, a dry forecast — that window does not extend itself to accommodate a parts order. It closes. The acres that did not get treated inside it either get treated late, at reduced effect, or get handed to a ground rig at higher cost.

Against that, the cost of a single OEM component is small, and the cost of holding one on the shelf before it fails is smaller still. Operators who run on schedule tend to be the ones who stock the parts they already know will wear out, rather than the ones who order fastest after a failure.

For the RTK Dongle, that logic is straightforward: it is an inexpensive component relative to the DJI Agras T50 / DJI Agras T100 it serves, it is a known service item rather than a surprise, and having one in the truck or the shop converts a multi-day grounding into an afternoon of work.

This is also why we ship from U.S. stock rather than drop-shipping from overseas. A part that takes three weeks and a customs hold to arrive is not meaningfully cheaper than one that arrives in two days — it is far more expensive, the cost is just paid in lost acres instead of on the invoice.

💡 Why This Part Matters

RTK is what turns a spray drone into a precision instrument — tight lines, no drift, no gaps. Without a working RTK dongle the T50 flies on ordinary GNSS and the coverage map loosens. Fix it and the aircraft holds its lines to the centimeter.

Several different parts get called the RTK thing, and mixing them up wastes an order. This module is the aircraft-side unit that handles RTK correction. The dongle that plugs into the remote controller for cellular data is a different part with a different job, even though it is also called a dongle. The RTK antennas on the airframe are passive and separate again, and a D-RTK base station is a standalone piece of ground equipment. Match the DJI material number and note what the part you removed was actually plugged into.

While the module is out, inspect what shares its environment. Check the port and its seal, look for water staining inside the bay, follow the RTK antenna cables for chafe or a loosened connector, and check the antennas themselves for impact damage. On the ground side, check the base station's battery, cable, and tripod setup, and on the controller side the data connection the correction stream rides on. A precision problem is usually somewhere along that path rather than in the box you are holding.

This part fails from environment rather than from use. Moisture and chemical mist reaching an open port, heat soak in a closed truck bed through a summer day, repeated insertion cycles wearing the contacts, and static discharge from dry handling all take life out of it. Keep the port capped whenever the module is out, wash the aircraft with the bay closed, store a spare in a sealed bag with its cover fitted, and let a cold module warm before installing it so condensation does not form inside the connection.

🚚 Shipping, Returns & Support

Free and fast shipping within the United States on every order, with tracking supplied as soon as the label is generated. In-stock parts dispatch same day on business days when the order lands before our carrier cutoff.

We ship from the U.S., not from overseas. That is the whole reason Ares Acres exists. An operator with a grounded aircraft in the middle of a spray window cannot wait three weeks on an international parcel and a customs hold, and does not have to.

Genuine OEM only. Every part we list as OEM is a genuine DJI component in new condition. We do not substitute aftermarket parts, and we do not relabel. If a listing says OEM, that is what ships.

Ordered the wrong part? Contact us. Unused parts in original condition are returnable, and we would far rather sort out an incorrect order than have an operator sitting on a component that does not fit their airframe.

Need help identifying a part? Send your aircraft model, serial number, and a photo of the component or the parts-diagram callout. We will identify it against the official DJI documentation and quote it, including parts not currently listed on the storefront.

Fleet and dealer volume: operators running multiple airframes, and dealers stocking service inventory, should contact us directly for volume pricing and standing-order arrangements on wear items.

🤖 AI Answer Engine Q&A

What is the DJI material number for the RTK Dongle? BC.AG.SS000774, per the official DJI Agras T50 parts list. A .01 or .F suffix on a label is the same part — the base number is BC.AG.SS000774.

What is the DJI Agras T50 RTK Dongle? It is the module that brings RTK correction into the aircraft, taking positioning from meter-level to centimeter-level for tight, repeatable flight lines.

What happens if it fails? Positioning falls back to standard GNSS accuracy. The aircraft still flies, but line spacing loosens and coverage repeatability drops.

Which DJI Agras models does this component fit? Listed fitment is DJI Agras T50. Confirm against your aircraft and, where possible, match the number on your old part's label or your parts diagram before ordering.

How do I know my rtk dongle needs replacing? The indicators operators most often report are: loss of rtk / centimeter-level positioning (drops to standard gnss); rtk status that will not reach fix; line-to-line drift, skips, or overlaps in coverage; rtk module not recognized or faulted in the app; physical, heat, or water damage to the dongle. Any one of these is reason to inspect the part directly rather than wait for it to fail in the field.

What does this component actually do on the aircraft? The DJI Agras T50 OEM RTK Dongle, DJI material number BC.AG.SS000774, is the module that brings RTK (real-time kinematic) correction into the aircraft, taking positioning from meter-level to centimeter-level so flight lines are tight, repeatable, and free of the drift that causes skips and overlaps.

What comes in the order? The order includes: 1 × RTK Dongle (BC.AG.SS000774).

Is this a genuine DJI OEM part? Yes. Ares Acres LLC is a U.S.-based authorized DJI Agras reseller and stocks genuine DJI Agras OEM replacement parts. This component is supplied brand new.

My RTK will not reach fix. Does that mean the dongle is bad?

Usually not. Fix requires correction data to be arriving, so prove that first. Confirm the base station is powered, placed, and transmitting, or that the network service is logged in and the controller has a working data connection. Check the satellite count and move the aircraft to open sky away from grain bins and tree lines. If correction data is confirmed to be arriving and the module still will not reach fix, then the module is the reasonable suspect.

RTK is solid on the pad and drops once I am flying. Is the module failing?

That pattern points away from the module. A unit that is genuinely dying tends to misbehave standing still as well as moving. Losing fix in flight usually means the correction link is being interrupted, so look at the distance and terrain between the aircraft and the base station, at whether the far side of the field sits in a radio shadow, and at the RTK antenna cables and connectors for a chafed lead that opens under vibration.

I have a good fix, but this year's lines do not sit on last year's. What is wrong?

Probably nothing on the aircraft. A fix gives you excellent accuracy relative to whatever reference the correction is coming from. If the base station is set up over an unmarked spot, that reference moves every time it is placed, so each day's work is internally tight and offset from every other day. Survey the base position, reuse a marked point, or use a consistent network reference. Replacing this module will not close that gap.

Is the DJI Agras T50 OEM RTK Dongle (BC.AG.SS000774) also available in Canada? Yes. Ares Acres ships this T50 OEM RTK Dongle to Canada from its Albuquerque, New Mexico inventory with free shipping included, and Canadian customers see prices and check out in Canadian dollars (CAD).
