Size, Weight, Power, and Cost (SWaP-C) evaluation for Global Navigation Satellite System (GNSS) receivers and antennas

<jats:p>The purpose of this technical note is to provide a brief assessment of Global Navigation Satellite System (GNSS) receivers and antennas, focused specifically on vertical positioning. The work compares multiple GNSS receivers at various cost points and antennas of different types during static testing against a known benchmark. Results show that high-cost GNSS receivers do provide better results than low-cost GNSS receivers, but there are likely use cases that the low-cost receiver should provide adequate results. The geodetic-survey GNSS-type antenna provide better results than the helical-style antennas, but similarly, there are use cases that justify usage of the smaller and lighter helical-style antennas.</jats:p>
