Professional Single Antenna Inertial Navigation System (INS‑P)
What separates the INS-P from the rest of the single-antenna line is the embedded gyro-compensated fluxgate compass. Three magnetometer axes, calibrated across the full operating temperature band, give the filter an absolute heading reference that does not depend on satellites at all — so heading survives outages that would leave a GNSS-only system drifting.
Heading that holds without GNSS
Static heading accuracy is 0.3° RMS, dynamic 0.1°, post-processed 0.03°. The magnetometers measure to ±1.6 Gauss with 0.2 nT in-run bias stability and 0.3 nT/√Hz noise density. For north-finding, north-keeping and extended GNSS-denied missions, this is the configuration Inertial Labs, a VIAVI Solutions company, points customers toward first.
Navigation performance
RTK fixes to 1 cm + 1 ppm horizontally and 2 cm vertically. SBAS delivers 0.6 m, DGPS 0.4 m, TerraStar-X 2 cm, post-processing 5 mm. Free-inertial land position holds 0.2% DT with Tunnel Guide references. Pitch and roll: 0.05° static, 0.03° dynamic, 0.006° post-processed.
Typical deployments
UAS platforms operating beyond reliable GNSS coverage, artillery and aiming applications needing repeatable north reference, integrated LiDAR payloads, and fixed-wing aerial navigation. The OEM variant measures 85.5 × 47.7 × 46.9 mm at 174 g; the enclosed version is 120.5 × 53.2 × 49.3 mm at 280 g.
Interfaces
RS-232, RS-422, RS-485, CAN and Ethernet in various combinations. Data out at up to 200 Hz for INS solutions and 2000 Hz for raw IMU. Power draw is 3.5 W, rising to 4.5 W with the 64 GB data logger fitted. MIL-STD-1275 input protection is optional.
