Providing a future-proof solution to ever evolving GPS/GNSS technology and protocols

Integrating SDR into GPS/GNSS enables system upgrades and adaptations to emerging technology through software.
Per Vices’ SDR future proofs your systems, saving significant time and money in upgrade costs.

Per Vices SDRs allow users to transmit and receive, and process all signals on one fully-integrated, modular platform. The products’ configurable architecture can work across different satellite constellations and protocols without requiring any hardware changes. Onboard DSP and FPGA resources allow for upgrades for ever evolving protocol changes. Additionally, we offer modifications to meet customer demands for filters, phase noise, noise figure, SNR, and more to align with user requirements.

Offering precision, fast convergence times and meeting aggressive spectrum masking requirements, Crimson TNG, Chestnut, and Cyan offer high versatility and configurations to improve functionality and accuracy in GPS/GNSS systems.

With the ability to simulate complex environments, track and lock onto weak signals, or those in congested or contested environments, our radios performance can be trusted for simulations as well as accurate location data and results.

Our SDRs are industry leading in serviceability, integration, and support into new or legacy systems. Whether you need a commercial-off-the-shelf (COTS) or customized solution, our team will work with you to determine the ideal configuration for your needs, and assist in developing plans for pilot projects, system integration, and production deployment.

Project Overview/Goals​

To develop a custom platform to meet the strict RF performance requirements associated with the simulation of hostile environments for GPS effectiveness testing.

This project had a combination of high performance RF and digital requirements for testing of both high and low power signals across multiple GPS bands.

These requirements resulted in Per Vices coming up with a new, performance focused, hardware designto meet the customer requirements in delivering a high channel count transmitter with aggressive channel masking and very high dynamic range for use across the L1 and L2 GPS bands.
The final solution consisted of a new hardware design which enabled up to 16 transmit radio channels to be used with custom filtering to meet the performance requirements associated with the project. In addition, the solution combined both high power and low power signal outputs to be transmitted over the same radio port (SMA).
How was this accomplished?

The customer first worked with our stock Crimson TNG platform to validate the performance of a 4 channel system. The next step was working with us to optimize some of the RF performance on the Crimson TNG platform to ensure we could meet the project’s objectives, and the final step was for us to design a new system to meet all of the objectives.

We entered into a proof of concept contract to make changes to our Crimson TNG platform in order to demonstrate our ability to meet the phase coherency, phase skew, and amplitude skew requirements the customer needed from the platform. Following the proof of concept contract, we entered into a full integration contract in which we designed the new system including hardware, firmware, and software to meet the complete RF and digital requirements.

Why was Per Vices selected?

The customer was evaluating different options but ultimately chose Per Vices as the preferred designer and manufacturer for this project. This decision was made due to the following major factors:

  • Performance: we demonstrated our ability to meet the very aggressive RF performance requirements
  • Risk Management: the availability of a COTS product allowed the customer to have the project proceed with each
    stage incrementally while validating performance
  • Communication: each step of the way we provided fast and effective communication between both parties’ engineering and purchasing teams
  • Complexity: we provided a reduction in supply chain complexity by having only one supplier as opposed to 100s

Although there were 4 major factors that led to the customer selecting Per Vices, there were also many other reasons why we were selected.

  • Performance: in addition to offering the best performance SDRs available in each class, we also have the expertise to design out even higher performance systems as required by our customers. This project was no exception, as we were able to have the customer start working with our Crimson TNG platform to validate the performance of our systems while we leveraged our existing knowledge and IP to develop a solution meeting their strict requirements.
  • Path for reducing risk further: in addition to the high performance of the product, we also worked with the customer to reduce risk by continuously providing small developments to demonstrate the next step in the proof of concept (POC); allowing the customer to become familiar with working with our company. This ultimately led to full confidence in our ability to hit the requirements on time and within the quoted budget.
  • Quick responses and communication: not only during the initial conversations did we provide clear, concise, and quick responses to the questions asked but we provided regular updates throughout the course of each project. In addition, we were transparent on the pricing, expectations, timelines, and milestones which were communicated through a formal statement of work.
  • Performance: our products offer the best performance in their class and the initial product for this project was no exception. It was of course necessary to make some small adjustments to meet the customers project requirements and specifications, but through those changes we were able to deliver a product that delivered superior performance compared to other available solutions.
  • Lower costs and faster time to market: we were able to save a considerable amount of development time and costs by having the customer first start working with our stock products and then using our expertise in designing systems to meet the system requirements. The reuse of existing IP also allowed for a fast turn around time and lower overall project costs as the customer was able to benefit from our economies of scale.
  • Reduction in supply chain complexity: acting as a single vendor of a system that replaced hundreds of components, the customer saved a considerable amount of time and logistical complexity by only needing to order and source the components through a single vendor: us. We further reduced complexity by ensuring all goods are manufactured in Canada and with features that ensure it is not a controlled good, thus not being restricted in our ability to export to the customer. Flexibility of the product: the flexibility inherent to software defined radios allowed this customer to adjust the bandwidth, tuning frequency, and overall radio chain configuration to test performance of the stock product. This also reduced the risk of making any modifications since the stock product helped demonstrate fundamental concepts that were applied for fine tuning to meet the customer requirements.
