· RAIM
Abbreviation of Receiver Autonomous Integrity Monitoring. This system automatically
detects failed satellites and deselects their positioning data from calculations. Including
data from failed satellites will result in a decrease in positioning accuracy; the RAIM
accuracy standard indicates the accuracy degradation base for removal of failed satellites
from positioning calculations.
4.16.1 Setting the GPS Mode
· You can set the GPS mode to AUTO, GPS alone, beacon, or SBAS.
· The sensor must support SBAS to use SBAS positioning mode.
The selections are as follows:
(1) AUTO: The best method is selected from GPS alone, SBAS, and beacon.
(2) GPS Alone: Positioning is performed using only the GPS. SBAS positioning and
beacon-based DGPS positioning is not performed.
(3) BEACON: Beacon based DGPS or GPS only positioning is performed. SBAS
positioning is not performed.
(4) SBAS: SBAS or GPS only positioning is performed. Beacon-based DGPS positioning is
not performed.
· Please refer to "4.20 Equipment Configuration" and switch the unit to equipment configuration
