DigiTerra Explorer is a constantly improved product and during last months the program was fit tp some new hardwares as well. This time we will introduce the Altus's APS GeoPod with DigiTerra Explorer. The APS GeoPod provides a compact GNSS module designed to add high precision positioning to mobile computing platforms. With only a USB 2.0 interface, mobile platforms may add RTK precision to any on-board application. (Visit website)
The GNSS Status screen displays the current position and accuracy stats such as PDOP and Fix status (DGPS in this case). After the Connect button is selected and sufficient satellites tracked. The required NMEA Com port is chosen be tapping the Set option and selecting the required COM port as determined in RXAssistant.If a local map is loaded as shown above, your current position will be shown against the map subject to the correct map projection being used. 
Altus APS GeoPod Configuration
RXTools
To configure the Geopod, install RXTools on your tablet device. Attach the GeoPod to the Tablet PC as shown and connect the USB into an available USB port. RX Tools configures the COM Port automatically when you start the application.
Position Status
Once a connection is established, satellite signals are tracked until a position can be determined. This status is displayed in the Position Tab and also provides information on RMS accuracy, Mode(Standalone/SBAS), No of Satellites (GPS/GLONASS) and GNSS Signal quality.
NMEA Output
For NMEA output, there will be a separate COM Port available (generally the next consecutive COM Port number) which is what needs to be selected within the third party application being used. Each third party application has its own GPS settings menu which will need to be set according to the individual requirements.
