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. Photo: LabSat With three channels, a bandwidth of up to 56 MHz and 6-bit sampling, LabSat 3 Wideband can handle almost any combination of constellation and signal that exists today, with plenty of spare capacity for future planned signals. For example, users can now record GPS L1, L2 and L5 at the same time as GLONASS G1 and G2 and BeiDou B1 and B2. An interactive bandwidth calculator allows users to see which combinations of constellation and signal can be recorded. Users can also change the bandwidth and bit depth to see how it affects the selection available. Despite the huge capability of the unit, the LabSat 3 Wideband remains easy to use, retaining the one-touch recording and playback feature. A removable battery pack gives two hours of use, and the 1-TB solid-state disk drive can be swapped in seconds. Specifications Recording bandwidth: 10MHz, 30MHz or 56MHz Recording resolution: 2, 4 or 6 bits (depending on bandwidth) Signals recorded: GPS: L1 / L2 / L5 GLONASS: L1 / L2 / L3 BeiDou: B1 / B2 / B3 QZSS: L1 / L2 / L5 Galileo: E1 / E1a / E5a / E5b / E6 IRNSS: L5 SBAS: WAAS / EGNOS / GAGAN / MSAS / SDCM
