Problems solved by technology

[0003] However, when the base station uses the multi-signal information in the RTCMV3.2 protocol to transmit differential correction information, if some data in a frame of multi-signal information has a bit error, the entire frame of multi-signal information will be unusable
Especially when the base station transmits multi-signal information wirelessly, due to the error in the wireless transmission process, it is easy to cause the rover to fail to complete differential positioning based on the received multi-signal information

Embodiment Construction

[0040] The technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0041] To clarify, when a component is said to be "set with" another component, it can be directly on the other component or there can also be a centered component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordin...

Abstract

The invention relates to a control terminal and control method thereof, a mobile platform and control method thereof, after receiving multi-signal information (S101), the control terminal can construct the multi-signal information into a plurality of sub-multi-signal information units (S102) and transmit the plurality of sub-multi-signal information units to the mobile platform (S103), after receiving the plurality of sub-multi-signal information units (S901), the mobile platform reconstructs multi-signal information according to the received plurality of sub-multi-signal information units (S902), then during a process of transmitting the plurality of sub-multi-signal information units from the control terminal to the mobile platform, if one or more sub-multi-signal information units in the plurality of sub-multi-signal information units have an error code or be lost, the mobile platform still can reconstruct the multi-signal information according to other sub-multi-signal informationunits, and differential positioning can be completed according to the reconstructed multi-signal information, and fault tolerance and reliability of multi-signal information transmission are improved.

Description

technical field [0001] The present invention relates to the technical field of global satellite navigation systems, and more specifically relates to a control terminal and a control method thereof, a movable platform and a control method thereof. . Background technique [0002] Differential global navigation satellite system (DGNSS) consists of three parts: base station, data communication link and mobile station (user equipment). According to the positioning principle of DGNSS, the base station forms differential correction information (pseudorange, carrier phase differential data ), and send the differential correction information to the rover using a standard protocol. At present, the base station mainly uses the RTCM (radio technical commission for martine service) protocol to transmit the formed differential correction information to the rover. At present, in order to meet the development trend of the global navigation satellite system, RTCM has undergone several form...
