The present document, together with ETSI EN 301 489-1 , covers the assessment of Receive Only Mobile Earth Stations (ROMES) and GNSS receivers operating in the RNSS band (ROGNSS), as defined in annex B, and associated ancillary equipment in respect of ElectroMagnetic Compatibility (EMC). Technical specifications related to the antenna port and emissions from the enclosure port of ROMES are not included in the present document. Such technical specifications are found in the relevant product standards for the effective use of the radio spectrum. The present document specifies the applicable test conditions, performance assessment and performance criteria for ROMES and associated ancillary equipment. ROMESs can have several configurations, including: - portable equipment; - fixed equipment; - a number of modules including a display/control interface to the user.
