摘要
为了有效利用有限的教学科研经费,需要采购生命周期较长的接收机,采购人员需要对卫星导航系统和接收机功能有充分的认识。该文概括了卫星导航系统的现状与未来的发展,根据当前接收机的发展趋势,提出具有前瞻性的接收机采购方案,不但可以节省采购成本,也可为教学、科研提供更多的研究方向和更前沿的课题。
To keep advance in research, institutes need to buy advanced receivers. Some types of receivers have a very short lifecycle because they are not good in compatibility. Buyers should have some knowledge about navigation systems to buy appropriate receivers for researchers. This paper describes the status and future of satellite navigation systems. Some types of receivers not only have long lifecycle, but also save cost and provide more subjects for researchers. This paper gives some proposals for buyer to purchase such a receiver.
