Traditionally referred to as "DGPS QC Software", POSTMAN is a novel and innovative solution to provide complete visualisation, analysis and reporting of the position solution and associated parameters. 

 

Previous limitations in GNSS hardware meant that to achieve a position solution with Integrity-Management including real-time active Quality Control, a separate computer and software application was required that received raw GNSS and augmentation data and recomputerd the position solution.

 

This led to a position solution that suffered from high-latency, data dropouts and whilst the benefits of real-time QC were significant, the overall availability and quality of the position was severly hampered.

​

Larger hardware solutions with integrated computers were developed and this assisted with the issue of latency by computing the solution within the hardware device. The GNSS software application then became focussed on visualisation. The subsequent issue was then the limitation of what could be visualised and analysed due to the very restricted generic interfaces like NMEA.

​

Positioneering have adopted an optimum approach, which includes; fully integrated hardware with comprehensive position processing, an optimum interface (POST) and a suite of focussed applications that are non-critical to the geenration of position.
