NETSAT 1 hasn’t been demodulated, so probably stopped transmitting, since 2020-10-20. However with combining results of observations back then and more recent ones, we managed to identify all of NETSAT satellites:
NETSAT 1: Identified as OBJECT W (46506) based on https://network.satnogs.org/observations/3011550/ and https://network.satnogs.org/observations/3011610/
NETSAT 2: Identified as OBJECT X (46507) based on https://network.satnogs.org/observations/3035746/, https://network.satnogs.org/observations/3035754/ and https://network.satnogs.org/observations/3035772/
NETSAT 3: Identified as OBJECT V (46505) based on https://network.satnogs.org/observations/3035787/
NETSAT 4: Identified as OBJECT U (46504) based on https://network.satnogs.org/observations/3035874/
