GNSS SDR receivers for ionosphere, CRPA and GNSS–INS R&D
ARAMIS ISM & RAD GNSS SDR Receivers
ARAMIS ISM provides ionospheric-scintillation observables, monitoring displays and open receiver processing. The ARAMIS R&D receiver provides the open GNSS SDR chain without the ISM functions. RAD combines the ARAMIS SDR engine with PORTOS A8 hardware for multi-antenna, CRPA and tightly coupled GNSS–INS development.

Primary scientific configuration
GNSS SDR ionospheric scintillation monitoring with ARAMIS ISM.
ARAMIS ISM is the primary scientific receiver configuration.
It combines the open ARAMIS GNSS SDR receiver chain with ionospheric-scintillation observables, monitoring displays and configurable processing for amplitude, phase and propagation analysis. The ARAMIS R&D receiver is available for projects that do not require the ISM monitoring functions.
ARAMIS ISM brochureRapid Application Development
RAD GNSS SDR receiver for CRPA and GNSS–INS R&D.
RAD combines the ARAMIS SDR engine with PORTOS A8 multi-channel hardware.
The system supports configurable RF inputs for up to eight antennas, real-time or recorded-data processing and C++ access to navigation and baseband processors. A dedicated RS-422 adapter transfers IMU packets with the receiver stream for synchronized loose, tight and ultra-tight GNSS–INS coupling research.
- Up to eight configurable antenna and SDR channels
- CRPA, coherent acquisition and multi-antenna processing
- RS-422 IMU data acquisition and packet decoding
- Loose, tight and ultra-tight GNSS–INS coupling
- Navigation and baseband C++ APIs with RTKLIB integration
Receiver architecture
Open receiver architecture for monitoring and R&D.
The ARAMIS GNSS SDR receiver chain underlies ISM, the R&D receiver and RAD.
The R&D receiver provides the open receiver chain without ISM monitoring functions. RAD combines the same processing environment with PORTOS A8 for multi-antenna, CRPA and integrated-navigation work.
The processing environment operates without receiver hardware on ReGen-DIF or recorded PORTOS files, or in real time with PORTOS as its RF front end. It provides access at signal, baseband, observable and navigation-solution levels for algorithm development, scientific instrumentation and integrated GNSS laboratories.

ARAMIS and PORTOS evaluated for NavIC + GPS ionosphere and positioning research.
Dr. Mehul V. Desai, Dr. Darshna D. Jagiwala and Dr. Shweta N. Shah evaluated a customized integrated ARAMIS SDR receiver and PORTOS RF front end for NavIC L5 + GPS L1 research published in IETE Technical Review. The SAC/ISRO-funded work used the ARAMIS Navigation API and raw-data access, implemented grid-based ionospheric correction, and compared the results with an Accord receiver.

Work at the level your research requires.
ARAMIS can expose intermediate receiver data and processing interfaces that conventional commercial receivers keep closed.
- Signal acquisition and tracking information
- Correlator, baseband and measurement-level data
- Pseudorange, carrier phase, Doppler and quality observables
- Navigation and baseband software interfaces
- Real-time processing and repeatable post-processing
- Customer algorithms and specialized output formats
Integration & laboratories
Use ARAMIS ISM, the R&D receiver or RAD in a complete experiment.
ARAMIS ISM, the R&D receiver and RAD can be integrated with ReGen simulation, inertial sensors, PORTOS front ends, practical exercises and textbooks. The same receiver algorithms process simulated DIF, recorded DIF or live RF input, supporting direct comparison across software-only, post-processed and real-time experiments.

Define the signals, monitoring observables and research objective first.
Tell us which constellations and frequencies are required, whether ISM monitoring functions are required, which processing levels must be accessible, and whether the receiver requires multi-antenna, CRPA, IMU/INS, simulator or laboratory integration.
