OmniSTAR 8305HP User Manual Installation and Set Up Installation Considerations Before commencing installation of the OmniSTAR 8305HP 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.
OmniSTAR 8305HP 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.
OmniSTAR 8305HP 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.
OmniSTAR 8305HP User Manual Additional Features and Information This section contains information on the additional features of the 8305HP receiver. Strobes On the 8305HP, a set of inputs and outputs that provide status and synchronisation signals are given. These signals are called strobes. Access to the strobe signals is obtained through the I/O port.
OmniSTAR 8305HP User Manual Mounting Bracket Along with the 8305HP, a mounting kit has been provided to facilitate mounting the receiver to a surface. This section provides information on how to mount the receiver. Note: The mounting kit is not designed for use in high-dynamics or high- vibration environments.
OmniSTAR 8305HP 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 antennas of any frequency. Closer positioning may cause overloading of receiver RF circuits.
OmniSTAR 8305HP User Manual Operating considerations The 8305HP has proven to be a high-quality positioning device. The accuracy that the user can obtain depends on several factors, including: Number of visible satellites Multipath Dilution of Precision (DOP) Satellite elevations Differential correction Number of visible satellites A minimum of four satellites is required to calculate a 3-dimensional position.
OmniSTAR 8305HP User Manual Position Dilution of Precision (PDOP) The Position Dilution of Precision (PDOP) is a measure of the satellite geometry. The lower the PDOP value, the more accurate the GPS position will Satellite elevations The signal from a satellite that is low on the horizon will travel a greater distance through the atmosphere.
OmniSTAR 8305HP User Manual Operation Before operating the receiver for the first time, ensure that you have followed the installation instructions. Communications with the Receiver Communications with the receiver is straightforward, and consist of issuing commands through the communications ports from an external serial communication device.
OmniSTAR 8305HP User Manual Getting Started The purpose of this section is to get you started with the 8305HP as quickly as possible. The guide will address receiving the satellite data carrier, and then checking the functionality and status of the HP Process.

OmniSTAR 8305HP User Manual Setting up data output Factory default, the 8305HP is not configured to output any NMEA-0183 compatible messages on any of its COM ports. However, the receiver may be preconfigured for you by OmniSTAR, in which case the output of the COM port(s) will be set to match your equipment’s needs and the rest of this section...
OmniSTAR 8305HP User Manual receiver is switched off. Omitting the ‘saveconfig’ command means losing all the changes made since the last ‘saveconfig’ when the receiver is powered off. Seeding the receiver Normally, when a GPS receiver is powered up, it will take some time before it starts outputting a GPS position and even more time before the position accuracy has improved enough to report a converged HP position solution.
