System Description and Overview
PCS Generates attitude data in three axes. Measurements of roll, pitch and heading are all accurate to ±0.02° or better, regardless of the vessel latitude. Heave measurements supplied by PCS maintain an accuracy of 5% of the measured vertical displacement or ±5 cm (whichever is the larger) for movements that have a period of up to 20 seconds.
The system includes a compact disk containing the PCS Controller program, which runs on a PC under Microsoft Windows™. After you install PCS, you can use this program to configure the system and monitor its status during operation.
in two start-up modes:
- You can use the Controller program to enable Navigation Mode and to monitor the status and performance of the system, or
- You can operate the PCS in stand-alone mode. In this mode,after power-on the system will enable Navigation Mode and deliver measurements automatically through whichever ports you have selected.
Communication between PCS and the Controller program is through a 10BaseT Ethernet link.
PCS includes two GPS receiver cards:
- The primary receiver can receive and process differential corrections.This receiver provides the position and velocity information to PCS. It also provides the Pulse Per Second (PPS) strobe that PCS uses to synchronize data output to Universal Time,Coordinated (UTC) or GPS time.
- Along with the primary receiver, the secondary receiver allows PCS to compute GPS heading aiding by performing carrier phase differential measurements between the two GPS receivers.
The system includes two identical antennas with 15 metre (~49 ¼ feet) long connection cables. You must connect each receiver to a GPS antenna to receive GPS signals from the orbiting constellation of satellites.The antennas supplied with the system have excellent phase centre stability.If you use alternative antennas with PCS, cannot guarantee the heading or position performance of the system.
GPS system is a unique feature of PCS that allows the system to achieve exceptional accuracy in the measurement of heading. The GPS system uses two GPS receivers and antennas to determine a GPS-based heading that is accurate to 0.2° or better (using a two-metre [~6 ½ feet] antenna baseline) when blended with the inertial navigation solution. PCS uses this heading information as ‘aiding’ data, together with position and velocity information supplied by the primary GPS receiver.
The PCS have a six RS-232 serial ports COM (1), COM (2), COM (3), COM (4) allow communication between the PCS and external equipment.
COM1 To COM4;
To supply data using up to eight NMEA sentence types. You can select the sentence format to include position information ($INGGA or $INGGK); heading data ($INHDT); track and speed data ($INVTG); error ellipsoids ($INGST); attitude data ($PASHR or $PRDID), time data ($INZDA or $INGGK), date ,data ($INZDA or $INGGK) and DOP data ($INGGK).To provide attitude and heading data for the multibeam sonar. including TSS1, TSM 5265 and Atlas. You can set the Simrad and the TSM 5265 formats to include angles of attitude using either the TSS standard or the Tate-Bryant standard.
You can select another data formats(OPTIONAL) if wish.
