Multi-core DSP based inertial/satellite deep integration information processing hardware platform

Abstract

The invention belongs to the technical field of an inertial navigation system, and particularly relates to a multi-core DSP based inertial / satellite deep integration information processing hardware platform. The hardware platform provided by the invention comprises a satellite radio frequency front-end module, an ADC conversion module, a satellite baseband information processing module, a deep integration information processing module, an inertial information acquisition module and an external communication module, wherein the satellite radio frequency front-end module, the ADC conversion module, the satellite baseband information processing module and the deep integration information processing module are sequentially connected, and the inertial information acquisition module and the external communication module are connected with the satellite baseband information processing module. The hardware platform further comprises a clock module and a power supply module, wherein the clock module provides a clock for the whole platform, and the power supply module provides power for the whole platform. The hardware platform provided by the invention solves a technical problem that an existing hardware platform cannot meet requirements of an inertial / satellite deep integration navigation information processing algorithm for data sharing, clock synchronization, operation timeliness and operation capability. The hardware platform reduces the hardware volume, reduces the hardware power consumption, saves the hardware cost, and ensures requirements of the clock for consistency and timeliness.

Description

technical field [0001] The invention belongs to the technical field of inertial navigation systems, and in particular relates to a multi-core DSP-based inertial / satellite deep combination information processing hardware platform.
