Embodiment Construction

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

[0050] like 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 routes o...

Abstract

The invention discloses a peer-to-peer security satellite high-precision enhanced network method constructed based on a P2P technology. The method comprises the following schemes of (1) a single-difference scheme in an NRTK service mode, (2) a non-difference scheme in an NRTK service mode, and (3) a technical scheme in a PPP-RTK service mode. The bottleneck problem that data of each unit reference station cannot be shared is solved, the'edge matching problem 'of location services of different units is solved, and high-precision location services with unified reference and consistent precision of a nationwide'network' are realized; high-precision positioning integrated service of the whole society is realized, data security of grid-connected service is realized, data benchmark unification of various families is realized, the problem of base station construction redundancy is solved, and great economic and social significance is achieved.

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...
