Why use LabSat?

Realistic, Reliable & Repeatable Testing

Reliable

The use of LabSat Record & Replay is a great way to understand, test and validate the real-world operation of GNSS devices without the need for costly, repetitive live-sky field-testing. It is a reliable solution for product development, performance testing and benchmarking, and production line testing.

Repeatable

Real-world, live-sky GNSS signals can be recorded once on location and then replayed over and over for accurate, consistent testing indoors. The recording can capture a scenario to test a specific product feature, or represent the wider use of a how and where a product will be used.

Realistic

Recording captures representative scenarios including challenging conditions such as low signal strength, multipath effects and common signal artefacts in a live sky environment. This enables testing and optimization of PNT devices for resilience and reliability in live sky conditions, eliminating the need for physical replication.

Ease of Use Anywhere

Ease of Use

Using a LabSat requires no special training. It has been designed for ease of use with simple navigation on the unit and an intuitive web interface for test configurations.

Compact Size

LabSat simulators are small, portable and battery powered, making them ideal for live-sky recording in any conditions. Its small size allows LabSat to fit into the most compact of spaces for recording on the move, and if being used as part of a wider test set-up, it fits easily into any standard rack mount.

Plug and Play

LabSat 3 Wideband is supplied with a selection of sample scenario recordings so that testing can start straight out of the box.

The one touch Record & Replay user interface means recording starts and stops with the press of a button. View the Quick Start User Guide to see how easy it is to get started with a LabSat.

Cost-effective

Budget-friendly

Using recorded GNSS data for testing reduces the need for repetitive field-testing and saves both time and costs. LabSat was born out of a need for an easy to use and cost-effective GNSS simulator and over 25 years later, it maintains not only its ease of use, but also its highly competitive pricing.

Free Lifetime Support

All LabSat owners benefit from exceptional customer support that is provided free of charge with no support contracts. All future firmware and software updates are also provided for free so that owners continue to have access to all the latest features and upgrades.

Shared Working

LabSat is ideal for modern working including multi-location, global offices and remote working. When recording, LabSat is robust enough to be moved between test locations and, for replay, can simply be passed between engineers or test benches. Additionally, it is easy to share recorded scenarios for replay on another LabSat.

Features in detail


Wideband

LabSat 3 Wideband offers three bandwidth settings of 56 MHz, 30 MHz, and 10 MHz per channel. This versatility allows it to capture almost any combination of GNSS signals simultaneously, whilst ensuring the efficient use of recording resources.

GNSS signal bandwidths ranges from a few kHz to several MHz and depends on various factors, such as the signal modulation scheme used. A GPS L1 C/A code signal, for example, has a bandwidth of 24 MHz. However, due to the signal design, a recording bandwidth of 10 MHz will capture enough data to allow the receiver under test to acquire, track and navigate.

Other signals may have a different structure. For example, Galileo E1 PRS signal has a bandwidth of 46 MHz and a signal design spread across the bandwidth. Therefore, in order to accurately record this signal, a larger bandwidth is required but sits comfortably within the LabSat 3 Wideband’s range.

Easy Configuration

LabSat 3 Wideband has an array of settings for both GNSS signal and external data recording. For simple configuration and device control, LabSat 3 Wideband comes with an internal web server, which can be easily accessed via a standard web browser on your PC.

SatGen

SatGen Simulation Software allows you to create a GNSS RF I&Q or IF data file based on a user-generated trajectory that can be replayed on a LabSat GNSS Simulator. This allows you to simulate almost any kind of test at any time, date and location.

Scenarios can feature multi-stop routes and include the crossing of time zones, leap seconds and roll-overs.

Additional Signals

LabSat 3 Wideband can record a range of additional signals, synchronised to the GNSS input, including dual-CAN, RS232, digital inputs and correction signals such as DGNSS and RTK.

Simultaneously capturing additional signals can increase the level of playback realism and allows for a wider range of testing.

NMEA data is also recorded via the inbuilt GNSS receiver.

A Video VBOX can be used in combination with LabSat to record video of the test route. This helps to identify the effect of external conditions on your device, such as why exactly was there a drop-out or multi-path reflection at a particular point in the test, and what caused it.


API available

LabSat’s Application Programming Interface (API) provides control and testing automation that allows test scenarios to be programmed to automatically repeat or play in a set order. This improves efficiency with significant testing programs able to be run continuously, without the need for human supervision.

Additionally, the use of the Ethernet connection allows for centralised control of the API, enabling testing at global production facilities to be controlled remotely from a central office. This combination can significantly increase consistency in testing and reduce the scope for user error.

Multi-Constellation & Multi-Frequency

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) at quantisation levels of 1, 2 and 3 bits (3 bits I + 3 bits Q).

LabSat 3 Wideband can Record & Replay the following signals:

GPS: L1 / L2 / L5
GLONASS: L1 / L2 / L3
BeiDou: B1 / B2 / B3
QZSS: L1 / L2 / L5 / L6
Galileo: E1 / E5a / E5b / E6
NavIC: L5 & S-band
SBAS: WAAS, EGNOS, GAGAN, MSAS, SDCM


Conducted or Radiated Testing

If the device under test has an external antenna connection, the LabSat RF output can be connected directly to it for conducted testing.

If the device has an internal antenna and no connection port, either an active GPS antenna or a Passive GPS/GLONASS antenna can be connected to the LabSat RF output, and they will transmit the RF signal over short distances to allow for radiated testing.

Radiated testing will need to be in an RF-screened environment to avoid interference with live signals. This can be done in a fully screened RF room or a portable enclosure, such as the LabSat Test Enclosure. This allows for secure screened testing and is ideal when working with devices that do not have an external antenna connector - such as wearables, smartphones, and sports/fitness trackers.

Record & Replay Options

LabSat 3 Wideband is available in two models – Record & Replay or Replay Only.

The Record & Replay version gives full functionality in one box and is a great choice when starting out with GNSS testing. It can be used to record live-sky signals and build up a bank of recorded scenarios ready for Replay through any LabSat 3 Wideband.

The Replay Only version is ideal for bench testing or production line testing when only the replay of an existing scenario is needed.

Both models are compatible with SatGen Simulation Software, allowing users to generate custom scenarios for replay testing.
