Gama Aviation has been awarded a contract by the Home Office to complete Transmitting Portable Electronic Devices ("TPED") testing on several Emergency Services aircraft in-line with its delivery of the new Emergency Services Network (ESN). ESN is the next generation of critical communications for the three Emergency Services and other user organisations, and an element of ESN is the development of a 4G LTE Air to Ground (A2G) network and Aircraft Communication System (ACS). This TPED contract facilitates the carrying out of early Electro-Magnetic Compatibility testing on Emergency Services aircraft in preparation for ACS installation. The Home Office has engaged Gama Aviation to complete this testing on a number of different aircraft to gain approval from EASA (European Union Aviation Safety Agency). The contract has been awarded from April 2020 - April 2021.
