* Hardware GNSS receivers are in general more efficient from the point of view of both computational load and power consumption since they have been designed in a highly specialized way with the only purpose of implementing the GNSS processing.

* Software GNSS receivers allow a huge flexibility: many features of the receiver can be modified just through software. This provides the receiver with adaptive capabilities, depending on the user's needs and working conditions. In addition, the receiver can be easily upgraded via software.<ref>[http://www.gpsworld.com/gnss-system/receiver-design/real-time-software-receivers-8812 Real-Time Software Receivers]{{Dead link|date=December 2019 |bot=InternetArchiveBot |fix-attempted=yes }}, GPS World, September 1, 2009 by Pierre-André Farine, Marcel Baracchi-Frei, Grégoire Waelchli, Cyril Botteron</ref>

* Under some assumptions, Software GNSS receivers can be more profitable for some applications, as long as sufficient computational power is available (and can be shared among multiple applications). For example, the microprocessor of a [[smartphone]] can be used to provide GNSS navigation with the only need of including a frontend (instead of a full, more expensive, hardware receiver).
