Implement the ARAIM algorithm developed by GNSS subject matter experts on a Collins’ Dual Frequency Multi-Constellation (DFMC) Multi-Mode Receiver (MMR) baseline
The ARAIM algorithm should support three possible architectures enabling different levels of performance, leveraging the use of Integrity Support Messages (ISMs)
The solution to ensure navigation integrity for en-route flight, terminal and approach operations supporting lateral and vertical guidance operations down to 200 feet decision height

ARAIM – Advanced Receiver Autonomous Integrity Monitoring
An extension to the legacy GPS single constellation, single frequency
Receiver Autonomous Integrity Monitoring (RAIM)
ARAIM concept extends the RAIM concept to be applicable to
multiplicity of GNSS constellations, including two or more frequency
signals from the same satellite
Benefits of ARAIM is to ensure world-wide integrity and continuity for
aviation navigation – terminal, en-route, oceanic and approach
operations
The notion of Integrity Support Messages (ISMs) fundamentally
underpins the ARAIM concept

The concept of providing ISM parameters to the ARAIM algorithm has been proven; The
behaviour of ARAIM algorithm due varying ISM parameters still needs assessing
ARAIM algorithm implementation requires further development in order to achieve the
initial H-ARAIM RNP 0.3 operational capability
The overall design, development and experimentation has been a success
The CPU Loading on the GLAD “Receiver Prototype” has been a challenging aspect of the project.
The “Receiver Prototype” is a result of a rapid-prototyping effort and is not a representative effort of a typical Collins design practice which would include CPU loading analysis to ensure proper operation
The limitations of the GLAD “Receiver Prototype” are addressed through Software
implementations under the MUGG Programme
