A dead-reckoning terrain referenced navigation (TRN) system is presented that uses two
airborne laser scanners (ALS) to aid an inertial navigation system (INS). The system uses …

This paper discusses the various aspects of using airborne laser scanners (ALS) in terrain
referenced navigation (TRN) systems. The paper addresses the system performance of these …

A coherent combining and long coherent integration (CCLCI) scheme is presented for
standalone direct acquisition of binary offset carrier (BOC) signals under strong radio frequency …

In vision‐aided navigation, images from natural scenes are processed to produce feature
measurements for navigation aiding. However, feature measurements are subject to non‐…

In order to enable the operation of both civil and military Uninhabited Aerial Vehicles (UAVs)
and Inhabited Aerial Vehicles (IAVs) at any time in any environment, a Precision Navigation…

The last few years have seen the emergence of various new optical technologies such as
the development of sensors known as 3D range–imaging cameras or Flash LADARS (Laser …

Terrain database integrity monitors and terrain-referenced navigation systems are based on
performing a comparison between stored terrain elevations with data from airborne sensors …

A dead-reckoning terrain referenced navigation (TRN) system that uses airborne laser
ranging sensors to aid an aircraft inertial navigation system (INS) is presented. Improved …

Terrain database integrity monitors and terrain referenced navigation systems are both based
on performing a comparison between stored terrain elevation data and data obtained from …

This paper discusses the evaluation of two sets of terrain referenced navigators (TRN). The
first set of TRN systems use radar altimeter measurements, baro-altimeter measurements, …
