Receiver Position Accuracy

Many factors affect position accuracy. If full accuracy is not achieved within 30 min, consider the following possibilities:

• Obstructed view of sky–Trees, buildings, or other structures block receiver signals from available satellites.
• L1/L2 signal-to-noise ratio (SNR)–Radio interference from 2-way radios or other sources causes low SNR (check Satellite softkey–Graph).
• Satellite position in sky–Poor satellite geometry can reduce accuracy (check Satellite softkey–SkyPlot).
• Number of satellites in solution–Total number of satellites receiver uses to calculate position (check Satellite softkey–SkyPlot).
