Abstract :
A derivation from basic principles is presented of GLONASS receiver in-band susceptibility levels suitable for Category I approach use. The derived limits are -113.5 dBm for interference bandwidths less than 500 kHz and -110.5 dBm/MHz for greater than 500 kHz. The limits are more stringent at the wide and narrow bandwidth extremes than the existing ARINC standard. Also derived are wide and narrow bandwidth GPS limits which are consistent with RTCA/DO-229 except for a 2 dB lower CW level
