(Network Design Condition) Schedules for the field observation shall be included in the plan. The field observation shall be timed when the Position Dilution of Precision (PDOP is ____. A ____PDOP value indicates a higher probability of accuracy.

PDOP measures how satellite geometry affects the precision of a GPS fix. When satellites are well distributed across the sky, PDOP is low, and the position solution has higher potential accuracy. If the satellites are clustered or obstructed, PDOP increases, amplifying measurement errors and reducing accuracy. Therefore, field observations should be timed when PDOP is low to maximize accuracy. The statement that fits is that the PDOP value is low, and a low PDOP value indicates a higher probability of accuracy.
