Spire Seeks Authorization for Lemur Constellation Earth Stations

To make up the ground segment of its Lemur satellite system, Spire Global is asking the FCC International Bureau for authority to operate 13 earth stations scattered around the U.S. In its IB filing Wednesday, Spire said Lemur will provide maritime and meteorological monitoring and earth imaging services, and needs authority to use the 402-403 MHz band for uplinks and the 2020-2025 MHz band for downlinks. The company said its use of 402-403 will be of limited duration and is unlikely to cause interference because of the infrequent transmissions. It said its use of 2020-2025 MHz also is unlikely to cause interference since the spectrum "is currently fallow." Spire said it asked for additional frequency authorization for its Phase II Lemur satellites, but those won't be deployed in the immediate future so it isn't seeking authority to use those frequencies with the proposed earth stations.
