FAQs
See below for answers to frequently asked questions about LEO100.
Getting Started
Do I need to install software before I can use the LEO100?
That depends on the purchased configuration.
- Development kits purchased with a host computer include all required software pre-installed
- Systems purchased without a host computer require software installation before starting the tutorials.
See the Software Installation page for the full setup process.
Can I use the Locus Lock GUI, or do I need to use the CLI?
The Locus Lock GUI is the recommended starting point. It provides the most direct workflow for configuring the system, verifying hardware connectivity, and collecting or processing data.
CLI workflows are also supported and are useful for automation, embedded deployments, and advanced workflows.
Are GNSS antennas included with the LEO100?
No. GNSS antennas are required for operation, but they are not included with the LEO100 hardware package.
What antennas does Locus Lock recommend?
The RadioLion board is a triple-frequency, dual-antenna front-end board, meaning it simultaneously digitizes signals at three frequency bands (L1, L2, and L5) from two antennas. Using two antennas is especially advantageous for rover receivers, as this (1) allows rover heading to be determined directly, (2) affords spatial diversity for more reliable precise solutions, and (3) offers a powerful defense against GNSS spoofing. A reference receiver can also benefit from dual-antenna input, but it's not so important as for a rover receiver.
Almost any GNSS antenna is compatable with RadioLion, but your antenna choice is going greatly affect performance. Here is a list of some triple-frequency antennas suitable for use with the RadioLion front-end:
| Device | Price | Link |
|---|---|---|
| Trimble AV28 | ~$450 | Trimble AV28 |
| Harxon GPS1000 | ~$210 | https://en.harxon.com/product/detail/98 |
| Tallysman TW3972 | ~$370 | https://www.calian.com/advanced-technologies/gnss_product/tw3972-triple-band-gnss-antenna-l-band/ |
| Trimble AG25 | ~$1000 | https://oemgnss.trimble.com/en/products/antennas/ag25 |
| U-blox ANN MB 02 | ~$60 | Digikey | UBLOX ANN MB 02 |
Note that this list is not inclusive of all options, it's just a list of antennas that have been qualified by Locus Lock
How do I know whether to use the beginner tutorials or the advanced tutorials?
The beginner tutorials are intended for initial familiarization with the standard GUI workflow. The advanced tutorials assume prior familiarity with configuring inputs, outputs, and basic PpRx operation.
Updates and Maintenance
How do software updates work?
PpRx can be updated from the GUI or by rerunning the device installer from the CLI. The Locus Lock GUI is updated by rerunning the latest GUI installer. See Update Software for the supported workflows.
Where can I find the latest feature and fix information?
The most recent feature and fix information for the PpRx GUI, CLI, and PpEngine can be found in the Release Notes.
Troubleshooting
What should I do if the system is not producing the output I expect?
Start with the basics:
- Confirm the hardware is connected and powered correctly.
- Verify that the correct software components are installed for the LEO100 variant in use.
- Verify in the GUI or CLI configuration that the intended outputs are enabled.
