Unleash UAS Connectivity with skyStation

skyStation supports various ARS including SkyLink-915, SkyLink-5060, and their micro versions, as well as muLTElink series.

Yes, all skyStation products comply with FAA TSO-C213a and are designed according to RTCA DO-362A standards.

skyStation units come with all necessary mounting kits and detailed instructions for both PoE and LTE models, ensuring straightforward tower installations.

skyStation automatically registers with the SkyLine Cloud Managed BVLOS Service for seamless operation and control across multiple ground stations.

The GRS (Ground Radio Station) uses SkyDM (SkyLine DataMux) to manage both link switching (between mediums/paths) and roaming (between multiple GRS within a medium). SkyDM is the key component that multiplexes the C2 links during a flight.

Link Switching
Link Switching chooses the primary link medium/paths (e.g., LTE vs Satcom) on the ground.
• Inputs: 1-second average of received user data on all links.
• Scope: Evaluates and switches between different link mediums/paths (e.g., LTE vs. Satcom).
• Prioritization: When the current active link becomes inactive (no data for >1 second), chooses an active link with the highest received rate (if multiple).
• Evaluation cadence: Every 1 second with double-hysteresis, consistent with muLTElink.
• Trigger: Switch occurs when a link is disqualified (0 user data, poor RSSI, or loss of connectivity).
• Behavior: Prioritizes stability with hysteresis to avoid unnecessary flapping.

Roaming (Within a Link)
Roaming chooses the lead GRS within a given link when multiple GRS are available.
• Scope: Roaming operates within a single link when multiple GRS are available.
• Inputs: Network connectivity status, RSSI strength, and reception of ARS heartbeats.
• Qualification: Each GRS is qualified using this combination of factors.
• Evaluation cadence: Every 1.5 seconds.
• Hysteresis: Single hysteresis applied to reduce unnecessary swaps.
• Selection: Chooses the lead GRS from qualified candidates; prefers strongest RSSI if all else equal.

Key Takeaway
• Primary vs. Lead distinction: Note that link switching chooses the primary link medium, while roaming chooses the lead GRS within that link.

Regular maintenance includes checking and cleaning the enclosures, verifying the integrity of the power supply, and updating the firmware via the Ethernet interface.

Ensure all firmware is up to date, check power supply and connections, and verify network settings. For persistent issues, contact uAvionix support for detailed diagnostics and assistance.
