Embodiment Construction

[0032] The deviation measurement unit of the frequency of the reference oscillator signal relative to the rated value actually executes the scheme of the complete receiver, including: a first frequency divider, whose output terminal is connected to the first input terminal of the phase detector through a frequency tuning unit; the phase detector The second input terminal of the second frequency divider is connected to the output terminal of the second frequency divider, and the output terminal is connected to the control input terminal of the frequency tuning unit and the signal input terminal of the deviation data forming unit of the reference oscillator signal frequency relative to the rated value through the integral network; At the same time, the input end of the first frequency divider and the output end of the deviation data forming unit of the reference oscillator signal frequency relative to the rated value respectively constitute the first input end and output end of th...

Abstract

The present invention relates to a GPS receiver with an emergency communication channel for receiving / transmitting emergency messages about critical situations. The receiver includes the traditional circuit of radio-navigation receivers operating by GPS standards and further includes a unit for determining the frequency shift of a signal from a reference generator relative to a nominal value. The first input of said unit is connected to the output of the reference generator, while the second input is connected through a signal transmission bus to the corresponding output of a unit for transmitting and receiving messages on the communication channel. The output of the unit for determining the frequency shift is connected to storage means for storing data about frequency shift of the signal from the reference generator relative to the nominal value, wherein said means are provided in the navigation processor memory unit.

Description

technical field [0001] The present invention relates to the field of wireless navigation, more particularly to a personal safety system that indicates the location of a target based on signals emitted by a satellite wireless navigation system (GPS system) and generates emergency information including location data in an emergency. Background technique [0002] An important application of user equipment operating from GPS signals is its use in object tracking systems including surveillance systems and personal security systems. [0003] A system for tracking and monitoring traffic (see for example [1] Application (DE) 3501035 in Germany, Int. Cl. G08 G 1 / 00, published 17 July 1986; [2] Application (EP) in EPO 0379198, Int.Cl.G01S 5 / 02, G01 S 5 / 14, published on July 25, 1990; [3] Application at EPO (EP) 0509775, Int.Cl.G01 S 5 / 14, 1992 4 [4] United States Patent (US) 5319374, Int.Cl.G01 S 1 / 24, G01 S 5 / 02, G01 S 3 / 02, G04 C 11 / 02, published on June 7, 1994 ) are known, where...
