Graticule Planning a GPS Survey Part 2 Dilution of Precision Errors

Hdop Gps. HDOP using Doppler positioning algorithm from 5 to 8 channels A HDOP of between one and two is excellent, and the greater the number, the less accurate One of the main contributing factors to GPS position accuracy is the geometric configuration (the position in the sky) of the satellites used to obtain a position.

The curved boundaries, which show abrupt transitions in DOP, are the edges of the footprints of various GPS satellites One important factor in determining positional accuracy is the constellation, or geometry, of the group of satellites from which signals are being received.

The 2,880 color images of HDOP (and VDOP) were converted into an animation that runs 4 minutes and 48 seconds at 10 frames per second One important factor in determining positional accuracy is the constellation, or geometry, of the group of satellites from which signals are being received. HDOP is calculated based on the positions of the GPS satellites that are currently visible to the receiver
