Unfortunately the processing of the data of all the IGEX stations has not been possible. Only dual frequency receivers with GPS time tags have been considered. Single frequency receivers do not make possible the creation of the ionospheric free combination. The inclusion of receivers working in GLONASS time reference would present conflicts for the measurement sampling times and the estimated parameters epochs.
These limitations have reduced the spectrum of receivers to the following models:

ESOC has been the operational data centre for the Leeds receivers during the IGEX campaign. Three receivers have contributed to the campaign from the beginning in October 98 ending the operation in August 99. The data of the following receivers was forwarded to the Global Data centres:
| 4 char ID | Receiver | Antenna |
| LDS1 | ESA/ISN | Trimble 4000SLD L1/L2 common for all receivers |
| LDS2 | Trimble 4000SSE | |
| LDS3 | Ashtech GG24 |
