Communication Support in Disaster Management
NESAC is having state-of-the-art sitcom facility for communication support in case of disaster. NESAC being situated in a region which is vulnerable to natural disaster like earthquake, flood, cyclones, landslide etc, one of its mandate is to support the region at the time of disasters through its sitcom facilities. .
For this purpose, NESAC has one ISRO-DMS VPN node which is connected to National Disaster Management Authority, New Delhi as well as State Disaster Management Authority of all NER states through VSAT based satcom link using bandwidth of GSAT satellite. Video Conferencing & data transfer is possible with this facility. For doing multi-party video conferencing simultaneously, a video wall is also installed at NER-DRR facility. .
NESAC also has a transportable Wireless in Local Loop using VSAT (WLL-VSAT) facility which can be taken to a disaster location where conventional communication facilities have been severed due to some natural disaster and can provide video conferencing, voice telephony and data transfer capabilities within its area of operation. .
Apart from this, NESAC also has portable satellite phones like INSAT Type-D terminal, GSAT-6 based Satellite Mobile Radio, Broadcast Receiver, Reporting Terminal & Sat-Sleeve terminals. NESAC has also distributed 10 numbers of SMRs to Meghalaya Police for their strategic use. .
Satcom Studio Facility
NESAC has a full- fledged studio facility for content generation and broadcasting. It is equipped with all required hardware and software for quality multimedia content generation on various topics for capacity building. NESAC has prepared multimedia content for various user departments at the studio with the help of specialists from NDRF,ABITA-GKUP etc as well as Scientists from NESAC. .
Ka-Band Propagation Experiment
ISRO-CNES-ONERA joint Ka-Band Propagation Experiment is operational at NESAC with sophisticated equipment like Beacon Receivers, Rain Gauge, Laser Precipitation Monitor, Humidity Profiling Radiometer etc. It is basically a study of attenuation of Ka-Band satellite to earth communication signal (20-30 GHz range) due to various meteorological conditions like rain, hail, clouds etc. The ITU model for rain attenuation has been proved to be insufficient to predict signal attenuation in tropical high rainfall regions like India. Therefore, a more detailed in-situ study is required to properly model Ka-Band signal attenuation in India as there is a growing demand for using the Ka-Band signal for high bandwidth applications in India. The experiment is being carried out with the help of two beacon transmitters onboard the GSAT-14 satellite and is operational from 2016 onwards at NESAC. .
NESAC is having a ISRONET facility for connecting to other ISRO/DOS centers through satcom technology. Video Conferencing and data transfer is possible with the facility.
NaVIC Ground Station
NESAC houses one NaVIC ground station, also called IRCDR. The station is maintained by ISTRAC, ISRO and is manned by ISTRAC,ISRO Engineers. Communication link is established between IRCDR and INC, Byalalu through satcom and terracom links for remote controlling the IRCDR 11 meter parabolic reflector dish antenna.
