Optional Software
The software available for Qstar 8 GIS data collector includes GIS software, DIGITERRA EXPLORER7, Carlson SurvCE, Arcpad10, etc. While selecting the software, please kindly note the following reminding.

1. Since the precision and the reliability of the product may be affected by the multipath, obstructions, satellite geometry and atmospheric conditions, the specifications recommended is for the applications in the open air without any obstructions, EMI and multipath and with optimal GNSS satellite constellation. Moreover, the surveying is performed with the method for advanced metering. For example, to achieve the accurate data, for the baselines longer than 30km, the precise ephemeris and 24 hours surveying are required.
2. The parameter listed is obtained by utilizing GPS and is subject to SBAS system. The WAAS differential positioning accuracy is less than 5 m 3DRMS.
