There are also seamless transitions across coverage zones, ensuring consistent performance as a user moves. The service has a minimum availability of 99.9%.
Supported Signals: The service supports multiple GNSS constellations and signals, including GPS (L1C/A, L2C, L5), Galileo (E1, E5b, E5a, E6), and BeiDou (B1I, B2A, B1C, B3I).
Stream Delivery: Corrections are delivered via IP.
Interfaces: The service uses the NTRIP 1.0/2.0 protocol.
Datums: Skylark Nx RTK supports multiple datums including ITRF2020, WGS84, NAD83 (US), ETRS89 (Europe), and DREF91 (Germany).
Security & Management: Skylark holds ISO 27001 (information security) and ISO 20000 (service management) certifications. It also has a redundant AWS cloud architecture for resilience.
