Advanced Land Navigation System

Why in the news?

Recently, Acceptance of Necessity (AoN) was accorded to the procurement of Advanced Land Navigation System (ALNS) Mk-II for Armoured Fighting Vehicles (AFVs) of the Indian Army.

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 an inertial sensor as well as GPS receiver and selects the most accurate data for calculations of navigational parameters.

GPS Mode: In this, the system is independent of inertial sensor inputs.

• ALNS Mk-II is compatible with Indian Regional Navigation Satellite System (IRNSS), NAVigation using Indian Constellation (NavlC), 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 [indian-Indigenously Designed Developed and Manufactured (lDDM)] category.
