LabSat3-Wideband-front-W

LabSat has launched the LabSat 3 Wideband simulator, which can simultaneously record multiple signals from different constellations. Small, battery powered and with a removable solid-state disk, LabSat 3 Wideband allows users to quickly gather detailed, real-world satellite data and replay those signals on the bench. With three channels, a bandwidth of up to 56 MHz and 6-bit sampling, LabSat 3 Wideband can handle almost any... read more

Note: In May 2013 this newsletter published a column on “What’s New in GNSS Simulation.” This month, Editor Tony Murfin takes a brief look at a new start-up in GNSS simulation, Skydel, and its software signal simulator. We also provide quick updates on the latest from those simulation companies and others. Skydel Software-defined simulator Skydel provides a software-defined simulator using... read more

It Doesn't Have to Be Expensive
GNSS signal simulators can be expensive and beyond the limited budgets of many researchers. In this month’s column, we look at one company’s approach to providing GNSS signal simulation at a low cost — one that virtually any researcher can afford.GNSS signal simulators can be expensive and beyond the limited budgets of many researchers.

FIGURE 1. Traditional in-vehicle receiver testing.

This article addresses how best to quantify “which navigation system performs best” in a realistic testing scenario. The methodology focuses on land vehicles navigating in urban environments, but applies equally well to pedestrian navigation and can be adapted for testing assisted-GNSS implementations. During a drive test, the truth-reference system and RF recording system log samples to disk, with no need for the receivers under test to be included during the actual drive. read more
