Work with satellite imagery in the multi-device suite. View all satellites, analyze the azimuth and elevation graph display for each of them, check the HDOP and VDOP parameters, etc. Monitor satellite signals, verify their eye on latitude, longitude, altitude, etc.
VisualGPS incorporates many advanced features found in professional programs. Its sole purpose is to display graphically specific NMEA 0183 sentences and show the effects of selective availability (SA).
Main Features:
- Azimuth and Elevation Graph - View all satellites that are in view. Each satellite identifies its pseudo random number (PRN) and its azimuth and elevation. Also plot and print the physical mask angle.
- Survey - The survey window displays both position and xDOP (HDOP and VDOP) parameters. The ability for user selectable HDOP/VDOP color thresholds for position averaging make a great utility. Also monitor Standard Deviation and effects of Selective Availability. That's not all - print the results graphically. (Click here for example print output) (in PDF format - 157K)
- Signal Quality/SNR Window - Monitor satellite signal to noise ratios and see them graphically on the screen. The signal quality window will grow or shrink to accommodate number of satellites in view
- Navigation - Monitor latitude, longitude and altitude
- NMEA Command Monitor - View NMEA sentences as they are received
Requirements:
- GPS Receiver connected to a RS-232 port with NMEA 0183 output - NMEA demo file included for those who do not have a GPS receiver
- Windows 2000 sp4, Windows XP, Vista or Windows 7
- 486 100MHz or higher microprocessor
- SVGA at least 1024X768 resolution
- 16 megabytes of RAM
- 6 megabytes of disk space
- One available RS-232 port (or captured NMEA text file - included)
