For high-efficiency field operations with DJI AGRAS T100 and DJI AGRAS T70P, DJI D-RTK 3 AG is the dedicated RTK base station that improves positioning reliability and repeatability across large blocks, rolling terrain, and long routes. It broadcasts corrections over O4 (2.4G/5.8G) and supports multiple GNSS constellations plus L-band, enabling both PPP and Network RTK style workflows depending on coverage and conditions.
Key benefits for AGRAS operators
- Multi-constellation GNSS + L-band support: GPS (L1/L2/L5), BeiDou, Galileo, GLONASS, QZSS, plus L-band support for robust satellite tracking.
- Long-range field broadcast: Effective signal range rated 15 km (FCC), 12 km (SRRC), 8 km (CE/JP) in typical published conditions.
- Two positioning paths for real-world operations:
PPP mode is suitable for areas without Network RTK service, and the manual recommends saving coordinates for repeat setups.
Network RTK / Custom Network RTK is intended for areas with Network RTK service.
- Weather-ready base station design: IP67 ingress protection rating is listed for D-RTK 3 AG on both AGRAS T100 and T70P spec pages.
Accuracy information you can quote in proposals
DJI lists positioning accuracy references for D-RTK 3 AG including:
- PPP satellite-based service accuracy: convergence time 20 minutes, horizontal 30 cm (RMS), elevation 40 cm (RMS)
- Network RTK calibration: horizontal 0.8 cm + 1 ppm (RMS), vertical 1.5 cm + 1 ppm (RMS), with the ppm term explained as distance-dependent degradation.
This is why searches like “RTK base station”, “RTK drone”, and “RTK GPS drone” tend to convert for AGRAS buyers who need repeatable routes, stable positioning, and consistent field documentation.
