Embodiment Construction

[0049] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0050] Such as figure 1 As shown, a kind of peer-to-peer security satellite high-precision enhanced network method based on P2P technology of the present invention comprises the following schemes:

[0051] (1) Single-difference scheme under the NRTK service mode: the observation data of the reference station is transmitted to each cooperative unit through a private network, and the cooperative unit forms differential data through single-difference with the data of the public reference station, and then broadcasts the single-difference data to other cooperative units ;Each cooperative unit can collect the differential data of all reference stations in the whole network, and then form their own differential service products through the NRTK calculation system;

[0052] (2) The non-difference scheme under the NRTK service mode: the technical route...

Abstract

The invention discloses a peer-to-peer security satellite high-precision enhanced network method based on P2P technology, including the following schemes: (1) single-difference scheme under NRTK service mode; (2) non-difference scheme under NRTK service mode; 3) Technical solutions under PPP‑RTK service mode. The present invention solves the bottleneck problem that the data of each unit's reference station cannot be shared, solves the "connection problem" of different unit's location services, and realizes the national "one network" with unified reference and high-precision location services with consistent accuracy; the present invention realizes the full The social high-precision positioning integrated service solves the data security of grid-connected services, solves the unification of data benchmarks of various companies, and solves the redundant problem of base station construction, which has great economic and social significance.

Description

technical field [0001] The invention relates to a satellite system, in particular to a peer-to-peer security satellite high-precision enhanced network method based on P2P technology. Background technique [0002] (1) Satellite differential technology background [0003] The construction technology of GNSS continuous operation reference stations has gradually developed and matured, and relevant industry standards and national standards have been issued in China. At present, provincial-level GNSS continuous operation reference station networks in most provinces, municipalities, and autonomous regions in China have been established and are widely used in various industries. The GNSS continuous operation reference station network organically combines GNSS technology, computer technology, network information technology, database, high-precision data processing and geographic information system, integrates various equipment and networks, and forms a base station infrastructure, d...
