uAvionix has announced the successful completion of the first series of flights with its newly developed SkyLink Control & Non-Payload Communications (CNPC) C-band radio, intended to meet the needs of safety-critical & BVLOS missions as well as operators and manufacturers with airframe certification in mind. The flight tests were conducted at a range of up to 25 miles at the Northern Plains UAS Test Site (NPUASTS) locations south of Grand Forks, ND. In August, uAvionix announced FAA and FCC approvals for testing C-band CNPC radios at several locations.
Regulators increasingly focus on the performance of safety-critical control data and recent RTCA standards recommend separating it from payload data for scalable commercial Unmanned Airborne Systems (UAS) operations. While most UAS still operate on public spectra such as ISM or 4G, current BVLOS waivers are primarily focused on recovery procedures to deal with the probability of a lost C2 link.
uAvionix SkyLink CNPC radios and the paired SkyLine application are entirely focused on preventing lost links, through aviation-grade software & hardware design, full compliance with RTCA Minimal Operational Performance Standards (MOPS DO-362A), and a network management system that monitors network and radio link health, built to Minimum Aviation System Performance Standards (MAPS DO-377A). In a previously released article, “A Radio Isn’t a Radio,” uAvionix discusses the need for protected spectrum and certified radio hardware for BVLOS operations.
“A reliable and predictable C2 link built to aviation standards (e.g., RTCA DO-362A) is a critical component in obtaining scalable BVLOS operations,” said Jim Cieplak, Program Manager of Vantis. “The uAvionix SkyLink radios and SkyLine Command & Control infrastructure are an essential component of the Vantis deployment to obtain a path to commercially viable BVLOS operations in the State of North Dakota.”
The SkyLink C Band CNPC radio is fully DO-362A compliant utilizing key concepts such as the ability to accept dynamic frequency inputs for Frequency Allocation Management (FAM), utilizing protected aviation spectrum for a stable and predictable C2 link performance to support BVLOS operations and safety-critical missions. SkyLink radios are built to anticipate TSO C-213A standards and targeted at demanding customers including those pursuing airframe certification.
The SkyLink CNPC radio system is developed to aviation-grade software & hardware requirements and consists of three main components:
- SkyLink airborne radio (ARS), a low Size, Weight and Power (SWaP), Multiple Input, Single Output (MISO) dual airborne radio system
- SkyLink ground radio (GRS), an IP67 all-weather dual dipole ground radio system, compliant with DO-362A GLXS
- SkyLink HUB, an ip67 network-ready communications hub, and TSO certifiable GPS receiver and antenna for multiple SkyLink GRS radios
The SkyLink radios can be used as a standalone radio system for a single Ground Control Station (GCS) or can be networked to provide linear or area coverage for larger-scale BVLOS operations, such as currently being deployed at VANTIS in North Dakota, where the combined system will operate as the C2 Communications Service Provider (C2CSP) for the State network.
“Together with our partners at the Northern Plains UAS Test Site, VANTIS, Thales, the FAA, and MITRE, we completed this significant milestone which will propel commercial UAS operations”, said Christian Ramsey, President of uAvionix. “We maintained a stable connection at a range of well over 25 miles at a 400’ operating altitude with a DO-362A compliant radio system, a first of its kind”
SkyLink provides the data exchange required for safety-critical operations to control, monitor, and manage a UAS in real-time. SkyLink radios seamlessly integrate with other certified avionics designed with airframe certification in mind such as truFYX GPS, ping200X, and the George autopilot.
