After laboratory testing, systems are commonly evaluated next in highway testing.

Systems designed for tactical aircraft must be designed to meet their performance specifications under the expected peak dynamic loading, which is generally determined by the pilot's limitations.

Systems designed for rockets must be tested under conditions expected during launch, sometimes as a “piggyback” payload during the launch of a rocket for another purpose. Accelerations can reach around for manned launch vehicles, and much higher for unmanned launch vehicles.

In all cases, GNSS has become an important part of field instrumentation. The Central Inertial Guidance Test Facility at Holoman AFB was once equipped with elaborate range instrumentation for this purpose, which is now performed at much lower cost using GNSS.
