Satellite Tracking Dish Refurbishment

 Mechanical diagnostics, systems analysis, mathematical modelling, hydraulic and mechanical refurbishment.

 Built by NASA in the 1950s using the hydraulic technology of the day, Avocet was a key consultant involved in restoring its mechanical performance for commercial use. The dish is used daily to receive data from satellites in polar orbits.  Visit ASTRA here
