Janus – QC and INS post-processing Software

Janus is our Quality Control and INS post-processing software for SPRINT. A simple user interface allows quick and easy data editing, post-processing and data export to enhance real time navigation. Janus utilises raw data from SPRINT and aiding sensors to both replicate the real-time navigation solution (forwards in time only) and significantly improve the navigation solution further using an advanced smoothed (forward and backwards) post-processed solution.

Janus Software Overview & Datasheet

Janus provides proven centimetre-level dynamic navigation with SPRINT 700 INS, Syrinx DVL and 6G LBL. Janus can also be used to improve and check navigation for SPRINT 300 and 500.

The real-time inertial navigation solution can be optimised using Janus’ outlier rejection functionality on all raw aiding sensor data and gives the user the ability to reconfigure the real-time settings to enable/disable sensors and to eliminate any systematic errors such as incorrect lever arms or mounting angles/incorrect error model.

Janus also exposes the aiding data availability, usage, rejection and reason. Janus displays the ‘health’ status of the INS algorithms, communication ports and internal electronics.

Post-processed aiding data not collected by the INS system in real-time can be imported.

Multiple navigation solutions can be stored and compared to help identify the optimum configuration.

Calibration of DVL-to-SPRINT mounting angles, latency and scale factor is performed with a post-processed forward/backward computation, with superior results than a real-time (forward only) computation.

There are Janus pre-defined navigation export formats available which are compatible with most 3rd party survey suites and added flexibility to create custom export formats.

Janus can be upgraded from the basic (DVL calibration and QC) version to full post-processed navigation capability.
