NovAtel PwrPak7 GNSS Receiver Enclosure
Rugged all-constellation OEM7 receiver enclosure with GRIT interference and spoofing detection for reference and monitoring stations
The PwrPak7 is Hexagon | NovAtel's compact, rugged receiver enclosure built around the OEM7700 GNSS engine - a turnkey way to field NovAtel's high-precision tracking and GRIT interference-monitoring firmware without board-level integration. It tracks all current and upcoming constellations and signals: GPS (L1 C/A, L1C, L2C, L2P, L5), GLONASS, Galileo (E1, E5 AltBOC, E5a, E5b, E6), BeiDou (B1I, B1C, B2I, B2a, B2b, B3I), QZSS, NavIC and SBAS, plus up to five L-Band channels for TerraStar corrections - and is software-upgradeable in the field as new signals come online. For aviation-infrastructure buyers the headline is resilience: spoofing detection, interference detection and mitigation are provided by NovAtel's GNSS Resilience and Integrity Technology (GRIT), so a PwrPak7 on a rooftop or airfield mast becomes a continuously watching interference-monitoring station, with the free GRIT Monitor dashboard providing spectrum, waterfall, signal-matrix and map visualisation.
Positioning scales from 1.5 m single-point to 1 cm + 1 ppm RTK and 2 cm TerraStar-X PPP, with <5 ns RMS time accuracy and up to 100 Hz measurement and position output. Connectivity is comprehensive for a 500 g, 147 x 125 x 55 mm unit: three serial ports, USB host and device, 10/100 Ethernet with onboard NTRIP client/server and web GUI, CAN, built-in Wi-Fi, PPS output, event I/O and Precision Time Protocol (PTP) support, plus 16 GB of internal storage for logging spectrum and observation data on site. The enclosure is genuinely field-hardened: IP67-rated, -40 C to +75 C operating, tested to MIL-STD-810H for vibration (Cat 24, 20 g RMS), shock (40 g) and acceleration (16 g), while drawing 3.25 W typical from a 9-36 VDC supply.
SPAN GNSS+INS variants (PwrPak7-E1/E2 and dual-antenna PwrPak7D versions) add an internal IMU interface to bridge GNSS outages for vehicle-mounted interference mapping or airside survey work. FCC, ISED, CE and global type approvals are held, and hardware variants without Wi-Fi or internal storage are available.
