GPS jamming trial: Is GLONASS affected?
I am curious as to whether the GPS jamming trial in Sennybridge over the next couple of weeks (see AIC P 072/2014) will affect GLONASS receivers. Does anyone know?
The notam mentions "..Jammer transmissions centred around 1176.45 MHz (L5), 12270.60 MHz (L2) & 1575.42 MHz (L1)", which from a bit of googling, seem to represent GPS (Navstar) frequencies. GLONASS frequencies appear to be slightly different (L1 1598.0625 - 1609.3125 L2 1242.9375 - 1251.6875).
I was wondering since jamming trials that happen from time to time may represent an additional reason for upgrading to a dual GPS/GLONASS receiver, particularly since interference can allegedly be expected out to a considerable distance (75nm radius in the low power jamming test in this case). If this is a military trial (the location suggests that!) then it does seem a bit odd that they would only block GPS but not GLONASS. You could read all sorts of things into the political background to that
