  • Page 2 Quantisation of I and Q signals is selectable from 1, 2 or 3 bits per signal. Depending on the combination of channel bandwidth and quantisation, LabSat 3 Wideband will adjust the number of available RF channels to keep the record data bandwidth within a rate that ensures continuous file transfer.

  • Page 3: How Does It Work

    LabSat 3 Wideband samples and stores the antenna signal at very high speed. When recorded RF signal is replayed by LabSat 3 Wideband into a standard GNSS receiver, such as a portable navigation system, the receiver will accept the signal as live, including all the velocity, delays and multipath effects.
  • Page 4 Example of Replay using the internal SSD with preloaded scenario. Briefly press the power button to power up LabSat 3 Wideband. Connect from the RF output on the rear of LabSat 3 Wideband to your GPS system antenna input. Use the 'UP/DOWN' arrows to select a file. Press the 'PLAY' button to start replay.

  • Page 18 LabSat 3 Wideband features 90 dB of attenuation control over the nominal signal output. This is adjustable in 1 dB steps. During replay, Pressing the 'DOWN' arrow will increase attenuation resulting in a lowering of the RF power output.

  • Page 19: Record Operation

    Record operation LabSat 3 Wideband uses an internal SSD (Solid State Drive) memory for storage and playback of GNSS data. This is formatted in an EXT4 linux format. LabSat 3 Wideband is supplied with a magnetic mounting GNSS antenna. The antenna is an active device with approximately 28 dB of gain.
  • Page 20 There are a number of GNSS systems currently in operation or in a test phase. LabSat 3 Wideband provides preselected frequencies to cover various GNSS signal recording requirements. The frequencies listed and the number of available channels depend on the required signal resolution and bandwidth. For example, it is possible to record 3 separate RF channels of 56 MHz each using 1 bit quantisation but if 3 bit quantisation is required at 56 MHz bandwidth, only one RF channel will be available.
