Overview 2 Figure 2.1 DSM 132 receiver As part of a marine construction or survey system, the receiver provides submeter (less than 3.28 ft) precision whenever differential corrections are applied. You can use a 1 PPS (pulse per second) strobe signal to synchronize time for logging event markers when you are using external instruments. You can use the receiver with a variety of marine survey equipment, including office software such as HYDROpro™, which also interfaces with echo sounde

2 Overview 22.4 Receiver input / output The DSM 132 standard power/data cable (PN 30945) connects to the receiver ports to supply power. It also enables the following data exchanges: ASCII, TSIP, and RTCM input from an external device. The receiver is able to receive ASCII data from an external device, convert this data into an NMEA message, and export that message to another device. TSIP command packets configure and monitor GPS and DGPS parameters. The receiver is also able to a

Overview 2 2.3 Differential GPS (DGPS) The DSM 132 receiver uses DGPS to achieve high accuracy. You can have a DSM 132RS (this is called the reference or base station) located at a known point. This receiver is used to determine GPS signal measurement errors. One or more mobile receivers (called rovers) collect data at unknown locations, while remaining within range of the reference station. The reference station broadcasts correction values, which are applied to the receiver positions

2 Overview 23.2 DGPS accuracy Submeter accuracy from the DSM 132 receiver utilizing differential correction is best achieved under the conditions described in Table 2.2. Table 2.2 DGPS accuracy Condition Optimum Description Value Number of > 5 To calculate a 3D position (latitude and longitude, altitude, satellites used and time), four or more satellites must be visible. To calculate a 2D position (latitude and longitude, and time), three or more satellites must be visible. The number of
