Satellite Tracking Information

A - Satellites Tracked

B - Velocity Solution

C - Position Solution

D - Corrections Age (sec)

E - VDOP

F - HDOP

G - PDOP

Satellite Tracking information is displayed at bottom of Sky Plot and Graph tabs.

• Satellites Tracked (A)–Total number of satellites tracked by receiver.
• Velocity Solution (B)–Number of satellites available to receiver that are above five degree elevation mask.
• Position Solution (C)–Number of satellites used to compute position.

Position Solution only uses high confidence data to calculate receiver position. Velocity Solution uses data from as many satellites as possible to calculate intermediate values based on previously calculated position solution. As a result, Velocity Solution count usually displays a higher number of satellites than Position Solution.

• Corrections Age (D)–Age of differential correction signal to receiver (normally less than 10 s).
• VDOP (E)–Vertical dilution of precision
• HDOP (F)–Horizontal dilution of precision
• PDOP (G)–Positional dilution of precision

These three values are an indicator of satellite geometry as viewed by receiver. A lower PDOP indicates better satellite geometry for calculating both horizontal and vertical position.
