TerraPos is our in-house developed GNSS/INS post processing software, providing a state-of-the-art kinematic Precise Point Positioning (PPP) solution for kinematic platforms. Process GNSS data for precise position and velocity, or use in combination with inertial data for a complete position, velocity and attitude solution. GNSS and inertial data are combined at the observation level ("tight coupling") for optimal use of GNSS data. Optionally, an existing GNSS trajectory may be combined with the inertial data in a "loosely coupled" solution. 

PPP gives you the freedom to operate independently of any reference stations or reference services. This is true autonomy - go anywhere, anytime.

Great performance and ease of use go hand-in-hand in TerraPos. Efforts has been made to ensure that most datasets will process nicely without any special tuning or expert judgments. Sophisticated and fully automatic data editing algorithms ensure robust handling of varying data quality. Overall, this makes TerraPos well suited for automated processing facilities. TerraPos is available for both Windows and Linux, and both with a graphical interface and as a collection of command line tools. All steps of the process can be automated: Data preparation and download of support data, processing, and finally, output using our powerful and flexible export module. 

TerraPos has been successfully tested using all classes of inertial sensors, from high-end navigation grade ring laser gyros (RLG), via navigation grade fiber optic gyros (FOG), and all the way down to consumer grade microeletcromechanical sensors (MEMS).

Dual-antenna processing is available in version 2.2 to support improved heading determination under low dynamics and/or when using low to moderate performance gyros.
