A small portable satellite navigation simulator with comprehensive functional design and complete simulation elements, suitable for various application scenarios such as outdoor real satellite simulation, fast navigation signal verification, and backpacking
The portable satellite navigation simulator adopts a powerful computing platform and a reconfigurable and configurable architecture design, which can flexibly configure and output signals from different system navigation frequency points, and supports simulation of four system full frequency band navigation satellite signals. At the same time, the equipment is equipped with a highly stable clock module, which can be fully synchronized with the actual Satellite navigation, and can realize the simulation of the real satellite navigation signal in the outfield environment, so as to facilitate the detection and troubleshooting of the outfield Beidou/GNSS navigation terminal.
The device has the characteristics of portability, miniaturization, simplicity, and ease of use, with a total weight (including battery) of no more than 5kg. It is suitable for applications such as outdoor real satellite simulation, rapid navigation signal verification, and backpack operation. Equipped with outfield Test automation evaluation software, it can meet the requirements for the detection and fault diagnosis of various functions and performance indicators of Beidou/GNSS navigation terminals in the outdoor environment.
