What ground radio systems is the SkyLink5060Micro compatible with?
It connects to SkyStation5060POE and SkyStation5060LTE ground radio systems.
Is a GPS required for the SkyLink5060Micro?
Yes, a GPS input is required for proper timing of frequency hopping and transmission of messages. Recommended options are truFYX EXT GPS (UAV-1004957-001).
How do I physically install the SkyLink5060Micro?
Install the ARS in the airframe in a location that allows easy access to the autopilot and minimal RF coax length for antenna installation. Longer coax lengths result in greater signal loss and reduced range.
How should the antenna be installed for the SkyLink5060Micro?
The kit includes one omnidirectional antenna. Install it on the airframe to reduce shadowing and interference. Avoid placing near other antennas or electronic equipment to minimize EMI. Mount the antenna in a vertical orientation.
How do I install the GPS for the SkyLink5060Micro?
Install the truFYX GPS on top of the airframe in a location that reduces shadowing and allows a clear view of the sky.
What is the wiring for the SkyLink5060Micro?
The SkyLink5060Micro uses a micro DB9 connector. Refer to the wiring diagram (Figure 17 in the ARS manual) for connections including power (9-31V), RS232 telemetry, and 1PPS UTC time pulse.
How do I register the SkyLink5060Micro with SkyLine?
Non-muLTElink ARS devices like the SkyLink5060Micro are registered by uAvionix prior to shipment. If assistance is needed, log a ticket at uAvionix.com/support. Registration steps include accessing the SkyLine URL, selecting Devices, clicking +, entering a name, the ARS RadioID from the label, the authorized C-Band frequency in Hz, and saving.
How do I configure the SkyLink5060Micro with an autopilot like Ardupilot?
Connect to a serial port (e.g., TELEM1 or TELEM2). Set SERIALx_BAUD to 57 (57600), SERIALx_PROTOCOL to 2 (MAVLink 2), SRx_PARAMS to 5, SERIALx_OPTIONS to 1024 (disable MAVLink forwarding). A power cycle/reboot is required after changes.
How do I configure the compatible ground radio system (e.g., SkyStation5060POE)?
Connect to POE++ switch on a DHCP network. Use a network scanner to find the IP (named SkyStation-XXXX). Browse to the IP, update the Websocket URL (obtained from support), save. Confirm in SkyLine under Devices GRS. For LTE models, power with battery and ensure LTE connection.
How does the SkyLink5060Micro operate in terms of link switching and roaming?
The ARS link switching logic monitors link health and switches to a better link if the current one degrades. It prioritizes links based on quality. For details on decision timing and behavior, refer to the ARS manual section 11. The system supports seamless roaming within a link and switching between links for reliable BVLOS operations.
What is the operational altitude limit for the SkyLink5060Micro?
It is suitable for operations below 1000 ft AGL due to its 100 mW output power.
Does operating the SkyLink5060Micro require a license?
Yes, C-Band operations require a license from the frequency regulator. Additionally, an experimental FCC license with FAA concurrence is needed before powering on in the US.
What are the recommended checks and maintenance procedures for SkyLink radios?
Regular maintenance includes checking the antenna connections, ensuring the device is free from physical damage, and verifying that the firmware is up to date. Conduct routine tests to ensure the system’s operational reliability, especially in diverse environmental conditions.
What should I do if there is no connection to SkyLine?
Check the network connection, ensure POE is properly connected, verify the IP address using a scanner, confirm the Websocket URL is correct, and check if the device appears in SkyLine under Devices GRS. For LTE models, ensure battery is charged and LTE signal is available.
What if I experience poor signal or range issues?
Verify antenna installation: ensure vertical orientation, minimal shadowing, short coax lengths, and separation from other electronics. Check for EMI interference. Ensure proper alignment of ground antennas towards the operational area.
Where can I get support for the SkyLink5060Micro?
For additional questions or support, submit a support ticket to uAvionix.com.
What if the device is not registering or appearing in SkyLine?
Ensure it is powered and connected properly. For non-muLTElink devices, confirm pre-registration by uAvionix. Check RadioID entry. Contact uAvionix support if issues persist.
What are the FAA requirements for operating SkyLink radios, particularly in the C-Band spectrum?
Operation in the C-Band spectrum requires adherence to FAA and FCC regulations, including obtaining the necessary frequency authorizations and ensuring compliance with any regional or national restrictions related to aviation-protected frequencies.
