2 Overview 16 DSM 132/132RS Receiver User Guide 22.1 St andard features A standard DSM 132 system provides: • 12-channel L1 1575.42 MHz (C/A code) GPS receiver with carrier phase filtering • Combi.
DSM 132/132RS Receiver User Guide 17 Overview 2 22.2 St andard Features DSM 132RS A DSM 132RS system provides all the features of the DSM 132 except: • the L1 Geodetic antenna with ground plane is supplied • the 30 meter antenna cable is supplied • the R TCM SC-104 output (base station corrections) is available 22.
2 Overview 18 DSM 132/132RS Receiver User Guide 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 R TCM input from an external device.
DSM 132/132RS Receiver User Guide 19 Overview 2 2.3 Differential GPS (DGPS) The DSM 132 receiver uses DGPS to achieve high accuracy . Y ou 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.
2 Overview 20 DSM 132/132RS Receiver User Guide 23.2 DGPS accuracy Submeter accuracy from the DSM 132 receiver utilizing differential correction is best achieved under the conditions described in T able 2.
DSM 132/132RS Receiver User Guide 21 Overview 2 23.3 Position Output Geographic data obtained from dif ferent sources must be referenced to the same datum, ellipsoid, and coordinate format. Different formats provide different coordinate values for any geographic location.
2 Overview 22 DSM 132/132RS Receiver User Guide Position Output Format The DSM 132 receiver outputs posi tions in Degrees, Minutes, and Decimal Minutes (DDD°MM.m'). This is the NMEA (National Marine Electronic Association) standard format and is commonly used worldwide for data transfer between e lectronic equipment.
