GMV develops a new GNSS receiver for high-precision applications with integrity

GMV has developed a light, portable and compact user terminal geared towards high-precision positioning applications (3-5 cm) and integrity. The terminal is capable of processing not only corrections provided by GMV’s

Precise Point Positioning (PPP) service but also corrections sent by first- and second-generation Satellite Based Augmentation Systems (SBASs) (Dual-Frequency Multi-Constellation: DFMC). It also incorporates integrity assurance algorithms developed and patented by GMV such as the Kalman Integrity Protection Level algorithm (KIPL).

The terminal is completely compatible with the SBAS DFMC (Dual-Frequency Multi-Constellation), currently deployed in Australia and New Zealand. GMV has participated in the development, deployment and installation of this system by providing the processing platform that generates the precise corrections and integrity parameters sent by the system. 

GMV’s aim in developing this terminal is to plug the commercial gap for secondgeneration SBAS-DFMC-compatible user terminals, in particular satisfying the existing demand in Australia and New Zealand for terminals of this type.

GMV has recently handed over the first batch of terminals designed to test the DFMC system available in the region in various sectors, such as precision agriculture, construction and sea-, air-, rail- and road-transport.

The user terminal has a built in userfriendly interface for monitoring equipment performance and function and configuring its connectivity. The terminal can be set up to send position and integrity messages easily in standard NMEA format to external Apps.
