Why use a GPS simulator?

LabSat 3 records and replays real world data, allowing realistic and repeatable testing to be carried out under controlled conditions. Signal artefacts including multipath, ionospheric effects and signal dropouts are reproduced and there are no limits to the number of satellites used in the test.

Conventional testing usually requires driving the same route multiple times, where conditions vary and satellite constellations change between tests. This can make it very challenging to reproduce and find software errors or reception issues with the device under test. Using LabSat 3 saves many hours of work, allowing you to quickly pinpoint errors and verify 'corner cases' without leaving the test bench.

A very useful feature is the ability to record and replay additional streams of data using the high speed digital port(s) on LabSat3. In this way, CAN bus data, RS232 signals or digital event triggers can be fully synchronised during playback, bringing a whole new level of realism to your bench simulations.

How does it work?

LabSat 3 receives the signal from a standard satellite antenna, but instead of processing each of the received signals to calculate a position fix, LabSat 3 digitises and stores the original satellite signals at a very high bandwidth onto a removable SD card or USB hard drive.

The RF output of the LabSat 3 is then connected to the antenna input of the device under test and the recorded data is replayed back as an RF signal. The device under test will then start to track the satellites as though it was travelling along the same path taken by the LabSat 3 during the original recording.

How easy is it to use?

One touch record/replay makes LabSat 3 extremely simple to operate. With its rugged construction, built in battery and clear display, it is very easy to use the LabSat 3 in the same environment as your product will experience in everyday use, with little or no training.

A free library of pre-recorded and simulated files from around the world is included to get you up and running as quickly as possible.

What satellite constellations can I record?

Each LabSat can be tuned to one of three user selectable frequencies:
  • 1575.420 MHz - GPS (L1) + Galileo + SBAS + QZSS
  • 1602.000 MHz - GLONASS (L1)
  • 1561.098 MHz - BeiDou (B1)

All units types can be factory upgraded to any other version.
All versions of LabSat 3 are supplied with a standard TCXO (Temperature-compensated crystal oscillator). However, an OCXO (Oven-controlled crystal oscillator) upgrade is available for all units. Please contact your local distributor or RACELOGIC office for more details.

Can I test with an internal antenna & no external antenna connector?

Yes, by using our active GPS antenna or the Passive GPS/GLONASS antennas listed in our LabSat 3 accessories section. These antennas connect directly to the RF ports on the LabSat 3 and will transmit the RF signal over short distances to the GNSS device being tested.

What else can I record at the same time?

You can log a variety of other information such as CAN, serial or digital data alongside the satellite signals. When the file is replayed, the embedded data is reproduced at the same time, synchronized to within 60nS. You can also embed a 1PPS signal using the internal GPS receiver.

Can I generate my own GPS test scenarios?

If you want to create your own custom test scenario using artificial signals, SatGen software allows you to quickly draw a route using Google maps, and then automatically creates an RF file which can then be transferred to an SD card and replayed on a LabSat 3.

Multiple satellites and multiple constellations can be simulated, and the user can also have precise control over velocity, heading and height profiles.

A suitable almanac can be automatically downloaded, or defined by the user. SatGen can also import KML files and NMEA files, and the time, date and dynamics are fully user definable.

How much data can I store on an SD card?

SanDisk 32GB Extreme SDHC cardEach channel uses ~14GBytes per hour, and the largest SD card which can be used is 128GB. Therefore you can record just over 9 hours with a single constellation and 4.5 hours with two constellations.

Available SD cards include 32GB, 64GB and 128 GB. Storage devices over 32GB need to be formatted in the FAT32 file system.

Please use SanDisk Extreme SD cards supplied by RACELOGIC (see Accessories below). The LabSat system is capable of formatting SD cards by selecting the file menu.

Case Study: Narrative "Clip" wearable camera

Narrative-LogoThe Narrative Clip is a typically innovative wearable, and one of the new wave of 'lifelogging' devices now finding their way into mass production. It is a tiny (36mm x 36mm x 9mm) five megapixel camera with enough memory to store four thousand images and battery power for two days of use. Designed and manufactured by a Swedish company originally called Memoto, who sourced crowdfunding to get the project off the ground, the Narrative Clip is small and non-intrusive to the point that it can be easily worn on one's clothes.

It is such a neat design that it has no buttons at all, only requiring to be put face down to enter standby mode. One of the standout features of the device is that the miniature enclosure includes a custom GPS engine and antenna, allowing for every image it takes to be geotagged. Future development of the cloud-based storage of these images will allow for searching by location.

Narrative-Clip-in-use

Bjorn Wesen, one of the developers on the project, explains how they got started:

"Because GPS does not work well indoors, at first we simply needed a way to test reception inside our office. Since we're not based in California, we can't just move the office outdoors! We started with a simple GPS-repeater, that is, an antenna mounted outside and an amplifier and re-transmitter indoors. This worked fine for some of the engineering tasks, but is not sufficient to reproduce testing scenarios or comparing sensitivity between different antenna-solutions, so we started looking at GPS record/replay products and that's when I contacted Racelogic."

This is a problem often faced by anyone developing a product that will include GPS: whilst it is entirely possible to walk outside and check that a signal is obtained, as Bjorn points out, it doesn't go far enough. The satellite almanac is constantly shifting, as are the signals themselves as they are 'bent' travelling through the ionosphere. Consistency is therefore hard to maintain, so a LabSat is the perfect solution.
