20 March 2007: NovAtel released version 7.80 of its GrafNav/GrafNet, GrafNav/GrafNet Static, GrafNav Lite, and GrafMov postprocessing software. This latest software release includes advancements such as precise point positioning (PPP), enhanced GLONASS processing, and other features.
“With the latest enhancements to our Waypoint postprocessing software, we are continuing to add value to our GPSplus products in order to deliver more accurate, competitively priced precise positioning solutions to our customers,” said Farlin Halsey, vice-president of marketing, NovAtel.
The new embedded PPP processor permits dual-frequency carrier phase processing without a base station. Users can expect 10-40 cm kinematic accuracies and 2-10 cm static accuracies, although accuracies can vary depending on age of the data, time length of collection, satellite geometry, frequency of cycle slips, receiver type, measurement quality, and other factors.
Enhanced GLONASS processing enables both GPS and GLONASS satellites to be used in Kinematic Ambiguity Resolution, reportedly resulting in faster, more reliable fixes and cleaner trajectory processing. The new Mission Planner supports GPS and GLONASS data. Also, GLONASS data can now be extracted from NovAtel OEMVTM-3, Leica 1200 GG, and RINEX formats, in addition to other manufacturer formats that were previously supported.
“We are very excited about the release of our new Version 7.80 postprocessing software. The PPP addition can reduce costs for customers by eliminating the need for base stations, while the enhanced GLONASS feature maximizes the capabilities of NovAtel’s latest OEMVTM receiver series,” said Pat Fenton, CTO, NovAtel.
