03

Production

Work with us to choose a standard or custom integration, scope engineering support, and scale production.

Start with an evaluation kit, then plan production with the Locus Lock team.

Validate performance on your platform, then work with us on a standard deployment or custom integration, with volume pricing for production orders.

The Software-Defined GNSS Engine

Introducing PpRx, the software behind Leo200

PpRx delivers the core signal processing, positioning and navigation capabilities across every Leo200 configuration.

  • Optimized for real-time deployment on low-SWaP, general-purpose compute
  • Multi-band, multi-constellation GNSS with multi-antenna and inertial support
  • Software-upgradeable signals, algorithms and threat-mitigation capabilities
Leo200-S vs. Leo200-D

Same software different hardware

Leo200-S and Leo200-D run the same PpRx receiver software. The difference is the included RF front end.

Frequently Asked Questions

Which onboard computers can run Leo200’s receiver software?

PpRx, the software behind Leo200, supports x86-64, ARM64, and RISC-V architectures. Standard deployments run on supported Linux hosts, either natively or in a Docker container. Compute requirements depend on the enabled signals, channel count, and processing configuration; software-only deployments require substantially fewer resources than the full evaluation environment. Contact us with your platform specifications to confirm compatibility.

What outputs are available, and how can I integrate them into my system?

PpRx provides position, velocity, timing, and GNSS observables, plus attitude and inertial estimates when configured with the appropriate inputs. Supported formats and interfaces include GBX, NMEA 0183, RINEX, ROS 2, ASPN 2023, MATLAB, CSV, and KML. CLI and programmatic interfaces support application integration, with custom middleware and interfaces available through Locus Lock.

Can I use my own RF front end or external IMU?

PpRx can work with qualified commercial and customer-specific RF front ends, and it supports external IMU measurements for GNSS/inertial navigation. Compatibility depends on your hardware, data interfaces, and configuration. Share your RF and sensor specifications with our team to determine whether an existing configuration fits or custom integration is needed.

What happens when my evaluation license expires?

The evaluation kit includes a one-year, fully featured software license. Continued use after that term requires an appropriate license. Contact us before expiration to discuss your evaluation needs or transition to a perpetual production license.

How are updates delivered to deployed units?

Updates are delivered through software, allowing supported signals, receiver capabilities, and threat-mitigation techniques to evolve on compatible hardware. Contact us to confirm update access, support coverage, and deployment options for your production license.

Can I purchase Leo200 for my country and application?

Purchase eligibility and any export licensing requirements depend on the destination, end user, and intended application. Contact Locus Lock with those details to confirm eligibility and any applicable operating restrictions before ordering.
