Advanced Land Navigation System

About Advanced Land Navigation System: 

• It is a Ring Laser Gyro (RLG) based navigation system.
• It is used for traversing a path defined by the coordinates of a military map in ESM format.
• The system provides Inertial, GPS and Hybrid Navigation data for the navigation requirements. 
• The system is spoof-proof with high levels of encryption.
• It can be operated in three different modes
  • Inertial Mode: In this, systems operate completely on the Inertial Sensor Inputs.
  • Hybrid Mode: It takes the inputs from inertial sensor as well as GPS receiver and selects the most accurate data for calculations of navigational parameters.
  • GPS Mode: In this, system is independent of inertial sensor inputs.
• ALNS Mk-II is compatible with Indian Regional Navigation Satellite System, NAVigation using Indian Constellation (IRNSS, NavlC), India in addition to Global Positioning System (GPS) and Global Navigation Satellite System (GLONASS).
• The ALNS Mk-II offers compatibility with Defence Series Maps resulting in very high accuracy in navigational applications for AFVs.
• This equipment will be procured from Bharat Electronics Limited (BEL), Chennai under Buy [lndian-Indigenously Designed Developed and Manufactured (lDDM)] category.
