SeaSTAR 3100LRS USER MANUAL Introduction About This Manual This manual has been produced to assist the typical user with the installation and operation of the 3100LRS DGPS Receiver. System Features The 3100LRS DGPS Receiver is a component part of the Fugro world-wide DGPS Service. The Fugro service is a full-time differential GPS (DGPS) broadcast system delivering corrections from an array of GPS reference stations located around the globe.
SeaSTAR 3100LRS USER MANUAL 3100LRS GETTING STARTED The purpose of this section is to get you started with the 3100LRS as quickly as possible. The guide will address receiving the satellite data carrier, and then checking the functionality of the internal GPS engine if fitted. We would ask you to quickly review the menu section of this manual, the menus are navigated by the Arrow buttons on the front panel, changes to options are made with the Up/Down keys, and items are entered using the centre key.
SeaSTAR 3100LRS USER MANUAL 2. Connect the power cable to a suitable 10-22V (10 – 36V if DC to DC converter fitted) DC power supply being sure to check correct polarity. 3. Install the DGPS antenna where it has a clear view of the sky in the direction of the satellite, refer to the NCC in your region for an azimuth/elevation chart for the satellite service you have subscribed to. 4.

SeaSTAR 3100LRS USER MANUAL Modes of Operation Setup Set the receiver to the required mode (either RAW, RTCM, VRC, VBS or HP). Some modes may not be available depending upon the security setting. Generally the receiver will be set to the correct mode prior to delivery to you, and will not be changeable.
SeaSTAR 3100LRS USER MANUAL Model 3100LRS / VBS or VRC Mode Setup In this mode a composite set of RTCM corrections is computed from the GPS network data sent over the link. The following information is required to compute these corrections; time (supplied via the link), GPS almanac data (supplied via the link), and receiver location either entered via the front panel or from an external GPS receiver interfaced via the AUX port.

SeaSTAR 3100LRS USER MANUAL Receiver Interfaces Power The 3100LRS will operate on any DC Voltage between 10V and 22V DC (10 – 36V if DC to DC converter fitted). When operational, the unit dissipates 7W of power. The 3100LRS can also withstand voltage surges up to 85V. The power input has reverse polarity protection. However, as the negative terminal is also attached to the housing ground, large currents can flow to any ground attachments made to the housing.
SeaSTAR 3100LRS USER MANUAL Antenna Antenna connection is made via a 5 metre RG58 low loss cable, which is terminated with a standard TNC 50-ohm male connector. If two antennae are supplied, each antenna will have its own cable. An antenna unit has an internal LNA (low noise amplifier) which is typically powered by 12V DC. When the 3100LRS is powered up, this voltage is present at the antenna socket on the rear panel. Therefore, care must be taken not to connect or disconnect an antenna when power is on.
SeaSTAR 3100LRS USER MANUAL The pin assignment for the Command port is shown in Table 2. Pin Number 1 2 3 4 5 6 7 8 9 Signal DCD TXD1 RXD1 DSR GND1 DTR CTS RTS Table 2 Command Port Pin Assignment Utility The Utility port is a standard DB9 female socket. The GPS engine can be configured via this port, using a laptop computer with proprietary software from the CD supplied. The pin assignment for the Utility port is shown in Table 3.
SeaSTAR 3100LRS USER MANUAL Auxiliary The Auxiliary port is a standard DB9 female socket. This port can be used to send enhanced RTCM (GPS correction) data to an external GPS receiver. However, it is necessary to first configure the Fugro SeaSTAR receiver board in the 3100LRS. This is carried out using a laptop computer with ‘Toolkit’ software via the Command port.
SeaSTAR 3100LRS USER MANUAL Installation Installation Considerations Before commencing installation of the 3100LRS in a vehicle or aircraft, the following should be considered : • Determine the preferred location for each unit. Consider cable length, connector attachment space (cable bend radius), stowing excess cable, moisture, chemical corrosion, vibration and heat exposure. • Before drilling holes, consider using existing hardware and locations where equipment was previously installed.
SeaSTAR 3100LRS USER MANUAL Counter Electromagnetic Force (CEMF) A potential problem inherent in any installation of electronic systems within a vehicle is Counter Electro-magnetic Force (CEMF). CEMF is caused when relays or solenoids, connected to the vehicle DC power distribution, are de-energised. The voltage produced may exceed – 400 volts.
SeaSTAR 3100LRS USER MANUAL Cable Installation • Cables must be correctly installed for optimum system operation. Therefore, the following should be noted: • Do not route an L-Band receiver remote antenna cable with the cabling of any other radio system. This may cause interference between both systems. • If at all possible, do not run L-Band receiver antenna cables parallel to other radio system cabling closer than 30 centimetres. • If cables must cross, ensure that they cross at an angle of 90°.
SeaSTAR 3100LRS USER MANUAL Antenna Location Antenna positioning is critical to system performance. The following conditions must be met for optimum system performance: • Antenna must be mounted at least 1.5 metres away from transmitting antennae of any frequency. Closer positioning may cause overloading of receiver RF circuits. • The antenna should be mounted at the highest practical point that will give a good view of the horizon and be as near level as possible.
