The receiver

The receiver is a has the following components: antenna circuit system, filter, amplifier, A / D converter. GPS satellite navigation signal, is an available to millions of users sharing information resources. For land, sea and space of the majority of users, as long as the user has to receive, tracking, transform and measurement of GPS signal receiving apparatus, namely, GPS signal receiver, can at any time with the GPS signal for navigation and positioning measurement.
Receiver
According to the intended use of the different requirements of users, the GPS signal receiver is also different. Now there are dozens of factory production GPS receiver, the product also has hundreds of. These products can be in accordance with the principles, purposes, functions and other classified.
According to the receiver use classification
In 1, the navigation receiver. This type of DVB T RECEIVERis mainly used for motor vehicle navigation, it can provide real time vehicle position and velocity. This type of receiver general use C / A code pseudorange measurement, single point real time positioning accuracy is low, typically + 25mm, SA + 100mm effect. The receiver is cheap, widely used. According to the different application fields, the receiver can be further divided into: vehicle type -- for vehicle navigation and positioning; navigation model -- for marine navigation and positioning; aviation model -- for aircraft navigation and positioning. As the aircraft running fast, therefore, in the air with receiver can adapt to high speed movement. Satellite type -- used for satellite navigation and positioning. Because the satellite high speed of 7km / s above, so the receiver requires higher.
2, geodesic type receiver. Geodesic type receiver is mainly used for precision geodetic surveying and precision engineering survey. High precision positioning. Instrument structure is complex, the price is more expensive. Timing receiver such receiver is mainly using GPS satellite with high precision time standard time, commonly used in the astronomical observatory and radio communications in time synchronization.
