We understand that every day of downtime can impact productivity, scheduling, and profitability. That's why we focus on providing fast fulfillment, responsive customer support, and reliable access to the parts operators need most.
A kit is a bet against downtime. The T50 OEM RTK & Relay Navigation Kit exists because the parts inside it are the ones that strand a T50 in the middle of a job — small, cheap, easy to lose, and impossible to improvise at the field edge. Buying them together is how experienced crews stop losing days to a part that costs less than the fuel burned driving back for it.
That is why Ares Acres assembles curated kits from genuine DJI OEM components and ships them fast to the U.S.A., helping operators shorten repairs, minimize downtime, and keep their aircraft spraying when every acre counts.
Configured for the DJI Agras T50. Every component in this kit remains available separately in the Ares Acres catalog.
The DJI Agras T50 OEM RTK & Relay Navigation Kit is an Ares Acres curated repair package that groups the components this job actually consumes into a single purchase. Precision guidance depends on three separate links working together: the aircraft RTK antenna, the RTK dongle, and the relay and controller antennas that carry the correction. This kit puts the whole navigation path in one order.
This product is assembled by Ares Acres from genuine DJI OEM components sold individually in our catalog. It is not represented as a factory-packaged DJI kit.
DJI Agras T50 OEM RTK Antenna Module (BC.AG.SS000694) — DJI material number BC.AG.SS000694. RTK antenna module / GNSS navigation component. It installs at the aircraft navigation system. Its job on the aircraft is straightforward: rTK correction reception for precision positioning, spraying, and mapping.
On the DJI Agras T50 OEM RTK Antenna Module (BC.AG.SS000694), construction is durable, weather-resistant build for agricultural duty; the design is direct-fit OEM navigation module; it mounts as direct-fit OEM replacement component; this line supplies 1 Module. Fitment covers DJI Agras T50, DJI Agras T25. Application: agricultural drone navigation system maintenance. Confirm the aircraft model and the position on your parts diagram before you order — DJI diagrams list visually similar components at different positions, and the material number is the only identifier that settles it.
Functionally, the DJI Agras T50 OEM RTK Antenna Module (BC.AG.SS000694) is responsible for a short and specific list of jobs: enable centimeter-level RTK positioning, deliver survey-grade position data to the flight controller, support precise, repeatable flight paths, keep swath lines straight and overlap correct, support accurate field mapping and surveying, maintain positioning stability in demanding conditions, resist weather, chemical, and UV exposure, replace degraded, damaged, or failing antennas, restore factory navigation accuracy, and install quickly with a direct fit. Those are the capabilities this kit restores when this component is replaced — which is why it is packed alongside the rest rather than sold only on its own.
In commercial service the DJI Agras T50 OEM RTK Antenna Module (BC.AG.SS000694) lives through chemical mist and spray drift, continuous airframe vibration, uV exposure across long seasons, moisture and washdown exposure, dust and airborne field debris, heat and cold cycling in the field, impact risk from branches and obstacles, connector stress from service cycles, and transport handling. Wear here is not a defect, it is the design working as intended until it runs out of margin — which is exactly the point at which having the replacement already on hand decides whether the aircraft flies tomorrow.
Left in service past its useful life, the DJI Agras T50 OEM RTK Antenna Module (BC.AG.SS000694) may contribute to degraded positioning accuracy, rTK signal loss or intermittent fix, drifting or wandering swath lines, overlap and skip in coverage, reduced mapping and survey accuracy, positioning fault warnings, interrupted spraying missions, unexpected downtime, and reduced fleet reliability. A fresh one instead maintains positioning worth putting on an invoice, swath lines straight enough to verify, chemical savings from correct overlap, survey-grade mapping output, two-model fleet coverage, professional fleet standards, increased aircraft uptime, reliable commercial performance, and long-term operational confidence.
Every flight line the aircraft flies is only as straight as the position data behind it — and the precision is only as good as the antenna receiving it.
Removal starts with power. Shut the aircraft down completely and disconnect the flight battery before you touch antenna wiring. RF connectors are not meant to be mated or unmated live, and on an aircraft this size the antenna run passes close enough to other harnesses that a slip with a tool while everything is energized is a much larger repair than the one you started.
Photograph the installation before anything moves. Cable routing on an Agras airframe is not decorative: the run is laid out to keep the coax away from carbon edges, out of the fold path of the arms, and clear of the spray plumbing, and it is held by clips and ties at specific points that set where the strain goes. Rebuilding it from memory is how a new antenna develops an intermittent three weeks later, in the middle of a job, for reasons nobody can find.
The DJI Agras T50 OEM RTK Antenna Module (BC.AG.SS000694) earns its place in this kit because of how it fails. Operators replace it when they see degraded or inconsistent RTK fix quality, intermittent RTK signal loss, longer times to achieve RTK fix, drifting or inaccurate positioning, swath lines that wander between passes, cracked or weathered antenna housing, corroded or damaged connectors, or impact damage from field obstacles. None of those are things you want to discover with the aircraft already apart and the spray window closing — which is the whole argument for having it on the shelf before the job starts.
DJI Agras T50 OEM RTK Dongle (BC.AG.SS000774) — DJI material number BC.AG.SS000774.
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.
The DJI Agras T50 OEM RTK Dongle (BC.AG.SS000774) earns its place in this kit because of how it fails. Operators replace it when they see 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, or physical, heat, or water damage to the dongle. None of those are things you want to discover with the aircraft already apart and the spray window closing — which is the whole argument for having it on the shelf before the job starts.
DJI Agras T50 Relay Module Antenna (Pair). Relay module transmission antenna. It installs at the signal relay module. Its job on the aircraft is straightforward: control and telemetry signal transmission.
On the DJI Agras T50 Relay Module Antenna (Pair), this line supplies 2 Antennas (matched pair). Fitment covers DJI Agras T50, DJI Agras T40, DJI Agras T25. Confirm the aircraft model and the position on your parts diagram before you order — DJI diagrams list visually similar components at different positions, and the material number is the only identifier that settles it.
Functionally, the DJI Agras T50 Relay Module Antenna (Pair) is responsible for a short and specific list of jobs: restore full control link range, cure signal dropouts at distance, replace a cracked or damaged antenna, recover degraded telemetry return, correct asymmetric signal between antennas, complete a relay module service, return transmission performance to spec, restore confidence at field boundaries, keep a spare pair on the shelf, and maintain link reliability through peak season. Those are the capabilities this kit restores when this component is replaced — which is why it is packed alongside the rest rather than sold only on its own.
In commercial service the DJI Agras T50 Relay Module Antenna (Pair) lives through transportation vibration and impact, repeated handling and folding, uV and weather exposure, chemical overspray contact, heat and humidity in the field, connector stress at the base, seasonal intensive operation, and long commercial operating hours. Wear here is not a defect, it is the design working as intended until it runs out of margin — which is exactly the point at which having the replacement already on hand decides whether the aircraft flies tomorrow.
Left in service past its useful life, the DJI Agras T50 Relay Module Antenna (Pair) may contribute to control link dropouts mid-mission, reduced effective operating range, aborted or repeated passes, telemetry gaps at distance, unnecessary return-to-home events, lost productive flying time, unplanned downtime, and reduced fleet availability. A fresh one instead maintains full control link range, stable signal at field boundaries, reliable telemetry return, reduced link dropouts mid-mission, confident operation at distance, consistent relay module performance, fewer aborted or repeated passes, and predictable service intervals.
The pair sets the polarization of the link, which is a bigger factor than most operators expect. A radio link loses a large fraction of its signal when the transmitting and receiving elements are not aligned to the same plane. Antennas that are leaning, folded over, or set at different angles to each other are throwing away link budget before terrain gets a vote. Set them vertical, set them parallel, and leave them there.
Height, not output, is what a relay antenna converts into range. At the frequencies these links run, the useful path wants to be clear of the ground and clear of the crop canopy, and the first few feet of elevation buy more than anything else you can do to the system. That is why a module on the truck roof outperforms a module on the tailgate, and why an antenna that has been folded over to fit in a case and never straightened costs range every time the relay is deployed.
There is also a survivability job that has nothing to do with radio. These antennas are the mechanical stress point of a device that gets set up and torn down several times a day, often one handed, often in wind. A sound base holds the element straight, keeps water out of the connection, and takes the leverage of a knock without passing it into the module's own port. When the base fails, the next thing to fail is the port on the module, and that is a different and more expensive repair.
The DJI Agras T50 Relay Module Antenna (Pair) earns its place in this kit because of how it fails. Operators replace it when they see signal dropouts at previously reliable range, reduced effective operating distance, weak or fluctuating signal strength readings, visible cracking or damage at the antenna base, bent or deformed antenna body, loose or corroded connector, telemetry gaps at field boundaries, or unexplained return-to-home triggers. None of those are things you want to discover with the aircraft already apart and the spray window closing — which is the whole argument for having it on the shelf before the job starts.
DJI Agras T50 OEM External RC PLUS Remote Antenna (YC.DZ.AA000253) — DJI material number YC.DZ.AA000253.
The antenna transmits and receives the control link. A damaged, cracked, or degraded antenna shortens range, weakens signal, and raises the risk of control dropouts at distance.
This antenna carries the command and control link, which is the one radio path on the aircraft that has no fallback the operator can use. Video can degrade and a job continues. Telemetry can stutter and a job continues. When command and control margin runs out the aircraft executes its own lost link behavior, and where it does that is decided by where it was when the link went, not by what the operator wanted at that moment.
Orientation is part of the job, not an accessory to it. An antenna radiates strongly out of its broad face and very weakly off its tip, so the useful field is a doughnut around the element rather than a beam out the end. Pointing the tips at the aircraft aims the weakest part of the pattern at exactly the thing you are trying to reach, and it is the single most common self inflicted range problem in the field.
The DJI Agras T50 OEM External RC PLUS Remote Antenna (YC.DZ.AA000253) earns its place in this kit because of how it fails. Operators replace it when they see reduced transmission range, weak or dropping signal at distance, cracked, bent, or damaged antenna, connector damage at the antenna base, or intermittent link warnings. None of those are things you want to discover with the aircraft already apart and the spray window closing — which is the whole argument for having it on the shelf before the job starts.
The T50 OEM RTK & Relay Navigation Kit is assembled around a job rather than around a product category. Its purpose is to put every part that job consumes into one box, so the repair is limited by the technician's time and not by a missing fastener.
Working through the kit, the components do the following:
Confirm the RTK source and correction settings after replacing the dongle. Antennas should be fitted before the aircraft is powered.
Across the components in this kit, the conditions that send an operator looking for these parts are:
Any one of these on a T50 is a reason to have the kit already on the shelf. The parts here are consumables and wear items by design — the question is never whether they will need replacing, only whether the replacement is in the truck when the aircraft comes down.
Kits are bought by the job, so here is the job. The sequence below is a general order of work for the T50 OEM RTK & Relay Navigation Kit on a T50; always follow DJI's official service documentation for torque values, disassembly steps, and safety procedures for your airframe revision.
Step 1 — DJI Agras T50 OEM RTK Antenna Module (BC.AG.SS000694). Work at the aircraft navigation system. Note the orientation of the part you are removing before it comes off; photographs at this stage save far more time than they cost. Once fitted, confirm that it rTK correction reception for precision positioning, spraying, and mapping as intended before closing up. Keep the removed part until the aircraft has been function-checked — it is the reference if anything about the replacement does not match.
Step 2 — DJI Agras T50 OEM RTK Dongle (BC.AG.SS000774). Identify the mounting position on your parts diagram before removal, and note the orientation of the old part before it comes off. Keep the removed part until the aircraft has been function-checked — it is the reference if anything about the replacement does not match.
Step 3 — DJI Agras T50 Relay Module Antenna (Pair). Work at the signal relay module. Note the orientation of the part you are removing before it comes off; photographs at this stage save far more time than they cost. Once fitted, confirm that it control and telemetry signal transmission as intended before closing up. Keep the removed part until the aircraft has been function-checked — it is the reference if anything about the replacement does not match.
Step 4 — DJI Agras T50 OEM External RC PLUS Remote Antenna (YC.DZ.AA000253). Identify the mounting position on your parts diagram before removal, and note the orientation of the old part before it comes off. Keep the removed part until the aircraft has been function-checked — it is the reference if anything about the replacement does not match.
Function-check the aircraft on the ground before it goes back to work. For the T50 OEM RTK & Relay Navigation Kit, that means confirming each replaced component behaves correctly under power and, where the component sits in the spray or spreading path, that there is no leak, binding, or unexpected noise before the first loaded flight of the day.

The T50 OEM RTK & Relay Navigation Kit suits operators running DJI Agras T50 airframes commercially: spraying contractors, fleet maintenance managers, agricultural drone technicians, repair facilities, and any crew that would rather open a box than place an order mid-season.
Precision guidance depends on three separate links working together, and a fault anywhere in the chain looks the same from the controller. Ordering the whole path together removes the second shipping window from the middle of a repair, which during a spray season is the part that actually costs money.
Bought separately, these 4 lines are 4 chances to order the wrong variant, 4 shipments to wait on, and 4 opportunities to discover the gap only after the aircraft is apart. Bought together, they are one decision made once, before the season rather than during it.
Ares Acres builds DJI Agras parts solutions around real maintenance jobs, so operators spend less time searching for the part they did not know they needed. Free and fast U.S. shipping, same-day dispatch on in-stock kits, from Albuquerque, New Mexico.
