Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.

[0017] The present invention mainly comprises the following aspects:

[0018] (1) Carrier phase difference relative positioning device

[0019] The relative positioning of high-precision satellite navigation adopts carrier phase measurement technology, and the relative positioning device is composed of a reference station and a mobile station. The reference station transmits the original observation data of satellite navigation to the mobile station in real time, which consists of a satellite navigation antenna, a satellite navigation receiver and a data transceiver device; the mobile station receives the data sent by the reference station and performs data gross error processing, Cycle slip detection and repair, carrier phase double-difference and integer cycle ambiguity ...

Abstract

The present invention provides a relative positioning device and a carrier wave integer ambiguity calculation method thereof. A base station is configured to receive satellite navigation original observation data and transmit the satellite navigation original observation data to a mobile station in real time; and the mobile station is configured to receive the satellite navigation original observation data, the gross error process of the satellite navigation original observation data is performed to complete the cycle slip detection and restoration of a carrier wave phase, and a double difference observation equation is established through the carrier wave phase double difference process so that the calculation of the integer ambiguity is realized and the relative positioning information is outputted. Through increasing of search and calculation speeds, high-precision relative positioning is rapidly realized, and the timeliness and the availability of a system are ensured.

Description

technical field [0001] The invention relates to a satellite navigation relative positioning device and an integer ambiguity resolution method thereof, belonging to the field of satellite navigation carrier phase high-precision relative positioning. Background technique [0002] The development trend of satellite navigation shows that dynamic positioning will have a wider application world than static positioning. The dynamic relative positioning of high-precision satellite navigation adopts the carrier phase measurement technology, and the key lies in the correct solution of the ambiguity of the whole circle. The solution of the whole cycle ambiguity usually adopts the double difference method. Its advantage is that the difference between the receivers can be calculated once, which can eliminate the influence of satellite clock error and ephemeris error, and reduce the influence of troposphere and ionosphere refraction, especially when the baseline is short. more obvious. ...
