To use GPS, we need to equip itself with the solution that that will be received their signal from satellites. This device must be a module GPS navigation. This device provides accurate information on the location of objects on Earth, based on information from satellites.
Each of the 24 navigation satellites equipped with a rubidium atomic clock, communicates with the ground segment (12 stations), to obtain information correction orbit satellites, or information about the amendments jonosfecznych. This information is obtained by the fact that the surveillance stations continuously collect data on the ephemerides and almanacs (location of satellites in the sky). Using the information about GPS almanacs can determine the time required to transmit signals from satellites to the GPS receiver. Since this time is proportional to the distance traveled, GPS modules can measure the radius between him and the satellite.
selection of GPS devices, including GPS modules, requires an analysis of the parameters, ie the type of module, power, and how you connect to other devices, such as telephone. Currently, the most common way to connect the GPS module to the other device is a Bluetooth interface. An important parameter determining each GPS unit to a significant extent on its quality is the amount of kanałówł (iość channels is equal to the maximum number of satellites, which may have contact us at the same time, the GPS module), frequency response, sensitivity, accuracy of location and time required for the First Amendment. If we uwgę power GPS module we need to determine voltage, current consumption and the type of antenna (some antennas are connected through SMA connectors.) Important parameters of each of the GPS module is called. cold start and warm start . Cold start is the time that must elapse from the first inclusion in navigation to determine position. Warm start is the time which must elapse between the re-integration module GPS to determine position.
