In order to process the L-band signals transmitted from the satellites and compute the navigation solution, a GNSS receiver can be designed to target different applications, markets, and solutions. From single or multi-frequency, single or multi-constellation, to survey or automotive applications, system specification details extend through a broad range of decisions and trade-offs, in order to achieve the best performance desired. The following sections tackle some considerations at a GNSS receiver system design level.
Overview
Most of the current GNSS receiver systems gather (at least) the blocks depicted in Figure 1, although some architecture variations might be present to accomodate different solutions. Besides these blocks, other common receiver components are the power unit (e.g. batteries) or the enclosure (e.g. ruggedization). All such parts and blocks are carefully chosen when a GNSS receiver is to be designed for a target application, and different considerations should be made on the choices and trade-offs involved.
