Caspinav is a hosted multi-tenant NTRIP caster and RTK network platform. It receives RTCM streams from base stations, distributes corrections to authenticated rovers, and exposes the whole operation through a tenant-scoped admin console.
From satellite to centimetre
A standalone GNSS receiver is accurate to a few metres. To reach centimetre precision, the rover needs corrections from a known base station, delivered with low latency. Caspinav is the layer that delivers them.
Each orange dot is one RTCM3 correction packet. The base receives the satellite signal, the caster distributes the corrections to every rover with a session on that mountpoint, and the rover combines them with its own observations to compute a fixed centimetre-level position.
Capabilities
Every capability listed below is in production and exercised by customers running real RTK networks.
RTCM3 MSM4 / 5 / 7 over NTRIP v2, Basic and token authentication, source-table on demand. Receivers from Trimble, Stonex, ComNav, Septentrio, u-blox just connect.
A virtual AUTO mountpoint that picks the nearest permitted base for each rover using a Voronoi tessellation, and re-evaluates as the rover moves.
Each tenant operates from your-brand.caspinav.com with its own logo, brand colour, and isolated user pool. Customers see your brand, not ours.
Real-time positions on a Leaflet map with rover trails, OSRM map-matching to road geometry, and a trips endpoint for replay.
Side channel on :2102 ingests RMC + GST so you keep speed, heading and per-axis sigma even when the primary stream is RTCM-only.
Upload base and rover logs and get a centimetre-level kinematic track in minutes. Logs never leave the platform.
Survey points and designate areas as parking station, bus lane, or stopping zone. Export as KML, GPX, or GeoJSON.
Per-username and per-IP bans, full session history, role-based admin, and a tenant-aware audit trail you can hand to a compliance team.
Documented endpoints for stats, rovers, sessions, and trips so your own dashboards or fleet systems can pull live data.

Multi-tenant architecture
A surveying company, a precision-agriculture operator, and a municipal traffic department can each operate their own admin console with their own brand on the same physical infrastructure. Tenant data is isolated; users from one tenant do not see data belonging to another.

Operational workflow
Point an NTRIP-capable base at caster.caspinav.com. The mountpoint appears in the source-table within seconds.
Create a tenant with its own subdomain, brand, and admin user. Deliver the URL to the customer.
Field rovers authenticate against the caster, the caster distributes corrections, and the rovers reach a fixed centimetre solution.
Monitor the live map, run PPK jobs, export billing, and manage designations from a single tenant-scoped console.
