GNSS Frequency Guide - Feature Preview

LabSat 3 Wideband comes with an integral web server to help you plan and set up your GNSS testing program.

You can see a preview of the LabSat 3 Wideband GNSS Frequency Guide here. This easy-to-use application can also function as a GNSS frequency selection tool or a look-up chart for GNSS signal location.

Wideband Freq

The image above shows an example test setup within the LabSat 3 Wideband web server. All GNSS signals and one signal band are selected, a bandwidth of 56 MHz around the centre frequency of 1580 MHz, and a current quantisation of 1.

Bandwidth Setting:

LabSat 3 Wideband has three bandwidth settings. 56 MHz, 30 MHz and 10 MHz.

The bandwidth of the GNSS signals varies, for example a GPS L1 C/A code signal has a bandwidth of 24 MHz. However, due to the signal design a bandwidth of 9.66 MHz will capture enough data to allow the receiver under test to acquire, track and navigate as with LabSat 3 single, dual and triple constellation devices.

Other signals with a different signal design like Galileo E1 PRS signal has a bandwidth of 46 MHz and a signal design spread across the bandwidth.
Many other signals have a similar requirement like GPS L1/L2 P code and M code. LabSat 3 Wideband has been designed to capture all these signals.

Frequency Setting:

LabSat 3 Wideband is designed to capture and replay GNSS signals in the upper L-Band (1559 - 1610 MHz) and lower L-Band (1164 - 1300 MHz).

Quantisation setting:

LabSat 3 Wideband can record and replay GNSS Signals at quantisation levels of:
  • 3 bits (3 bit I + 3 bit Q)
  • 2 bits (2 bit I + 2 bit Q)
  • 1 bits (1 bit I + 1 bit Q)

Small, lightweight enclosure

LabSat 3 Wideband is housed in a conveniently small enclosure measuring 167mm x 128mm x 46mm and weighing only 1.2kg, so it can be used to record GNSS signals anywhere. Subsequent replay is entirely realistic to allow for robust product development and testing.

The system is simple to use with one touch record and replay and SSD logging, and no requirement for a connected computer. An inbuilt battery pack gives two hours of use, and a 1TB solid-state hard drive is supplied as standard.

Recording and Replay of Additional Signals

LabSat 3 Wideband can record a range of additional signals, synchronised to the GNSS input: dual-CAN, RS232, and digital inputs are simultaneously captured increasing the level of playback realism and allowing for a wider range of testing. This flexibility means that the development of products incorporating this variety of signal streams can be conducted with absolute convenience on the bench, without the need for costly and time consuming field trials. NMEA data is also recorded via the inbuilt GNSS receiver.

LabSat 3 Wideband Additional Inputs

Future-Proofing Your Products

LabSat 3 GPS Simulator

Posted in Products

The most affordable, portable, and versatile multi-constellation Global Navigation Satellite Simulator on the market.

Labsat3-GPS-Simulator

If you are selling, testing or developing products incorporating satellite navigation chipsets, then you'll find LabSat 3 makes your job easier, quicker and more cost effective.

Features

  • Available for GPS L1, GLONASS L1,
    Galileo E1, BeiDou B1, QZSS and SBAS
  • Small, rugged, anodised aluminium construction
  • Fully standalone
  • Compact, lightweight and portable
  • Simple to use one touch recording
  • Single, dual or triple constellation
  • Internal battery life up to 2 hours

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.

LabSat3-SatNav

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.

SatGenv2 Screen montage

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.

Download a free demonstration of SatGen software (with a limited scenario length) here >

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.
