The number of GNSS signals, the frequency and sophistication of intentional and
unintentional threats to those signals, and the need for integration between GNSS and
other positioning, navigation and timing (PNT) sources — especially for indoor and
autonomous navigation — are continuing to increase, as is the number of new applications
for GNSS. In response, manufacturers of GNSS simulators are creating new and improved
models able to simulate all these new signals and scenarios.

Additionally, as GNSS chipsets continue to be further commoditized, simulator
manufacturers must address the needs of new entrants into the GNSS receiver market
that have lower accuracy requirements and require less technical expertise and, therefore,
require units that are smaller and cheaper and have simpler interfaces.
