LN-251 Embedded Inertial Navigation System/GPS System
Description The LN-251 is a completely integrated navigation system with an embedded 12-channel, all-in-view, Selective Availability/Anti-Spoofing Module (SAASM), P(Y) code GPS. The fully integrated, tightly coupled GPS inertial design provides superior positioning performance relative to other embedded Inertial Navigation System/Global Positioning System (INS/GPS) systems. Modular open system architecture provides for easy adaptation to other applications and evolving requirements.
Options
The LN-251 is available with an integrated high anti-jam GPS subsystem.
Applications
The LN-251 is an integrated, tightly coupled, embedded INS/GPS system that provides improved performance for mission equipment and flight control systems.
