Custom Projects

Projects

EIDEL handle projects on module, system, hardware and software level. The projects range from consept definition and development to production and delivery of operational units. A few examples are given below.

"Have-Quick" Remote Control System
This is a project which has been developed on specification from the Norwegian Defence Logistic Organisation (NDLO). The system is a time- and frequency information system for use in ground based anti jam communication systems. First batch in the delivery phase was in 1990/91. The equipment is now under contract with EIDEL as main contractor to the Norwegian defence and as sub-supplier in NATO projects in several countries, via Marconi Communications S.p.A. in Italy. Second generation equipments was delivered from 1999, handling all frequency bands.

Radio Management System
EIDEL is at present delivering a new management system for the ground to air radios in Norway, used for communication with military aircraft. The system was set into operation in Norway in 1999, and the nation wide installation was completed in 2003. The capasity will be increased from 2004 till 2008.

The system is designed to control a number of radios from an operation center, where the radios are located at remote sites, up to several 1000 km away. The system can allocate frequency hopping and/or encryption to any radio.

The system is distributing correct timing to all radios connected to the system. Time is received from GPS. Rubidium oscillators in the system enable the system to maintain correct time over a significant period, should the GPS time input fail.

The communication system is controlled by duplicated PC’s, with Windows platforms. The duplicated control computer (one active and one hot standby) together with other duplications and the free selection in the system of resources to the radio sites, makes the system redundant with minor impact from single equipment failures.

The remote control equipment at the radio sites is designed to connect to any radio make. By remote controlling the radios, sites don’t need to be manned or guarded, as all sensitive equipment is located in control centres. Control centres may be disconnected to reduce manpower requirements during periods with low activity.

At the control centre, all equipment is installed in 19 inch racks. All racks are delivered pre cabled for easy installation. The total installation, testing and commissioning of a large control centre will take typically one month.

Training requirements for technical personnel has proved to be very low as long as the technical operators are familiar with Windows based Man-Machine interface. A comprehensive built-in test system is included with the system.

Telemetry systems
Several PCM encoders and conditioning modules have been designed for specific customers.

A datacollection system with Solid State Recorder was qualified for operation at 8000G and –40°C.
Dedicated conditioning modules has been designed to interface asynchronous data streams to the EE240 Encoder.
The EE248 GPS receiver module for the EE240 Encoder was originally designed for tracking of objects like unmanned UAV's. GPS data is processed and telemetered both as raw data and clear text position.
A datacollection and data storage system was designed for use inside high speed ship propellers. A wireless remote control system was included.
Custom functions have been made to the EE350 Decoder software to decode and present non-standard data formats. GPS receiver messages are regenerated in the EE350 decoder software for output on the PC COM port to standard map plotters.

Artemis Diagnostic Package
This project was managed by ESTEC, the European space, research and technology centre of ESA. EIDEL had the main contractor responsibility for developing a system to evaluate solar cells contamination versus ion propulsion for future satellite applications in general the Artemis satellite in particular. The project is divided in two.

A feasibility study was focused on relevant phenomenas and how they could be measured. How to measure liquid level in weightless tanks was a separate task.
A diagnostic instrument including sensors were designed to measure possible effects from the ion propulsion engines on the spacecraft itself and optical systems onboard. The instrument was manufactured and qualified for flight.
