Abstract

In order to measure the position of a mobile target (3) with respect to a ship (2), the target (3) includes a global positioning system (GPS) data relay (4) and relays GPS information to a monitor unit (1) on the ship (2). The monitor unit (1) has a full GPS receiver (8) to receive GPS information relating to the ship's position as well as a receiver (7) to receive data from the target (3). It also includes a processor (9) to determine the positional co-ordinates of the ship (2) and the target (3) and thus to calculate their relative positions in terms of range and bearing of the target (3) from the ship (2). The relayed information may be encrypted for security reasons. Application to calibrating radar or sonar is mentioned. <IMAGE>

Description

MOBILE TARGET POSITIONING MONITORING SYSTEM The e present invention relates to mobile targets that are used, principally but not exclusively, for checking sensor errors and calibration and alignment of sensors and monitoring equipment.
Equipment is tested on a target of known position and the results from the equipnent under test are compared with the known data to find the errors and enable calibration or alignment of the equipment to be carried out.
Such targets are currently used to check sonar and radar sensor errors. For accurate assessment of the errors the position of the target must be known very accurately. At present the target position is determined using radar, but problems arise when the sensor accuracy approaches the radar errors.
The object of the invention is to provide a more accurate means of determining the position of a mobile target than has previously been achievable.
The invention provides a means for determining the position of a mobile target comprising a monitoring station unit and a target unit wherein the monitoring station unit includes: a receiver to receive global positioning information from earth satellites; a receiver to receive information from the target relating to the position of the target; and a processor to calculate the positions of the monitoring station unit and the target; and wherein the target unit includes: a receiver to receive global positioning information from earth satellites; and a transmitter to transmit the target positional information to the monitoring station unit.
Preferably the monitoring station unit includes a recorder to record the positional information and/or a display unit to display the information.
The e monitoring station may be any type of station from which monitoring of such targets is required such as a ship, an aircraft, a mobile lanbbased station or a permanent station.
Advantageously transmissions on the data link between the target unit transmitter and the monitoring unit receiver can be coded to provide signal security if required.
Preferably the monitoring station unit processor determines the positional co-ordinates of the monitoring station and the target for the global positioning information. Conveniently the positional co-ordinates may be derived in terms of latitude and longitude co-ordinates.
If the positional data is recorded, the data can be used for later analysis and comparison of data fran tested equipment. Alternatively the information can be displayed in real time to allow assessment of the performance of equipment.
The e invention will now be described by way of example with reference to the drawing, which shows a schematic diagram of a mobile target position monitoring system according to the invention.
As shown schematically in the drawing, a monitor unit 1 is positioned on board a ship 2. A mobile target 3 is positioned remotely from the ship 2.
The e target 3 contains a global positioning system (GPS) data relay 4 which camprises a receiver for receiving the GPS information and a transmitter for transmitting the information via a data link 5 to the monitor 1. The e target also has a battery power supply 6 to power the relay station 4.
The monitor unit 1 has a data link receiver 7 to receive the target GPS information transmitted by the target relay station 4. Also in the monitor unit 1 is a full GPS receiver 8 to receive positional information from the GPS satellites relating to the position of the ship 2.
The e data received by the data link receiver 7 and the GPS receiver 8 are passed to a processor 9. The processor 9 is programmed to determine the positional co-ordinates of the ship 2 and the target 3 and to calculate their relative positions in terms of range and bearing of the target 3 from the ship 2. The e processed data is recorded on a recorder 10 for later analysis if required and the data is displayed, in real time, on a display unit 11.
The e positional data determined by the monitor unit can be used to assess the errors in, for example, readings given by sonar and radar sensors by comparison of the sensor readings with the monitor unit readings. The sensors can then be calibrated correctly. The e data from the monitor unit can also be used to check the alignment of a vessel's computer command system and heading reference unit.
The invention can be adapted for use with any global positioning system and enables extremely accurate determination of the positions of the host vessel and the target.
The invention is obviously not restricted to the use of one target but may include a plurality of targets monitored from one monitoring station unit if required.
