Tightly-coupled GPS/NS receiver

11 June 2008 Telecoms, Datacoms, Wireless, IoT

NovAtel has announced the launch of SPAN-CPT, a powerful single-enclosure, tightly-coupled GPS/INS receiver. It integrates NovAtel's OEMV GNSS precision receiver technology with fibre-optic gyro and MEMS accelerometer inertial components from KVH Industries in one compact unit.

The tight-coupling of the GPS and INS (inertial navigation system) technologies within SPAN-CPT optimises the raw GPS and IMU data, delivering an advanced position, velocity and attitude solution. Comprised entirely of commercial components, it has no special export restrictions, minimising the operational complexities for customers whose products cross international boundaries.

In most GPS/INS systems, GPS data is used to aid and control errors in the INS; with SPAN-CPT, the INS data in turn aids the GPS. This tight-coupling of the two technologies enables continuous robust positioning in challenging navigation environments where GPS signals are unreliable or unavailable for short periods of time. The module also supports standard SPAN technology features including L-Band corrections, dual-frequency RTK, and PAC correlator technology.
