Description

Technical Field

[0001] The present invention relates to the field of environmental observation technology, and in particular to a Beidou satellite-based glacier environmental observation element transmission system. Background Art

Beidou satellite can provide high-precision positioning and time information, providing important technical support for glacier dynamic observation, ice and snow cover area monitoring, etc.

[0003] When existing glacier environment observation elements are transmitted, the large amount of data content is complex, which easily leads to long transmission time and network congestion.

[0015] S13. The coordinates corresponding to the multiple hardware devices and the collected glacier environmental elements are sent to the ground base station. The ground base station aggregates the glacier environmental elements and the corresponding coordinates collected by the multiple hardware devices into a first content package.
