摘要
目前掩星探测反演主要在地面进行,需要星上将掩星数据存储,过境时回传地面。针对星上存储空间要求较大、数传压力较大、反演实时性较差的问题,本文提出一种离散化的基于TEC的电离层星上反演算法,实时进行电离层反演,直接下传反演结果,达到减少回传数据量,降低卫星数传压力、提高反演实时性的目的。
The occultation inversion is mainly done on the ground, and need transit star general occultation data back to the ground when crossing the back ground. For the on-board storage requirements, large data transmission pressure, poor real-time inversion problem, this paper proposes a discrete inversion algorithm based on TEC satellite ionosphere, occultation inversion in real-time, directly transfer the inversion results, and to achieve the purpose of reducing the amount of data return, low pressure, improving the inversion of satellite data transmission in real time.
