Statement: Spectrum access for Enhanced Long-Range Navigation (eLoran) systems at 90-110 kHz

Statement published 23 October 2023

Having carefully considered all responses to the consultation we have decided to proceed with our proposals to introduce a new licence product authorising eLoran in the 90-110 kHz spectrum band.

Taking account of consultation responses and our own further considerations, we have made two changes to the licence conditions we proposed in the May 2023 consultation:

  • Increased the notice period for licence revocation to 5 years. The licences will be issued for an indefinite period, and may only be revoked on spectrum management grounds subject to a minimum of five years notice. This is an increase from the three years notice period proposed in the May 2023 consultation and is to provide greater certainty of tenure for investors and operators.
  • Increased the maximum EIRP permitted from any single transmitter to 1 MW (60 dBW).This represents a 4 dB increase from the maximum EIRP of 400 kW proposed in the May 2023 consultation and will allow the eLoran signals to be received in hard-to-reach areas such as in tunnels and deep inside buildings.
