Ashtech introduces Web Mission Planning

Nantes, France: At Intergeo, Ashtech announced the immediate availability of Web Mission Planning, the first self-contained, completely automatic web-accessible GNSS survey planning tool. Now, users can anywhere log in at www.ashtech.com and use the survey-planning tool free of charge to determine satellite visibilities.

The new tool developed by Ashtech uses Google Earth mapping and is interactive and completely self-contained. “Unlike existing planning tools, there is no need to import satellite almanacs or download anything, since Web Mission Planning automatically retrieves and loads the daily almanac into the application’s background,” said, Olivier Casabianca, Product Marketing Manager, GNSS boards and sensors.
Survey planning in advance is important to ensure optimum satellite geometry, to account for mask at the site and to avoid poor satellite tracking conditions in the field. Surveyors working in urban canyons or under dense tree canopy and GPS-only receiver users find that it is particularly important to prepare their survey by determining in advance the best time and product configuration for optimal satellite visibility and DOP.
Web Mission Planning requires just three steps to provide satellite visibilities.  
–       Select the site using either the integrated Google Maps or key in the location or coordinates.
–       Select the time and date range.
–       Select the desired satellite constellations, GPS, GLONASS and SBAS, that are to be included.  Satellite visibility results are offered in four different views: satellites and count; satellites and DOP (GDOP, PDOP, VDOP, HDOP, TDOP); polar diagram, and a 3D representation.
