The ATMACA has no (correct me if I'm wrong) radar or camera, so a network enabled missile that gives nothing in return is useless, no?
Guidance = Inertial Navigation System (INS)/Global Positioning System (GPS) + RAdar + Data Link
Seeker = active RF (i.e. an onboard radar)
It's the DL (datalink) that makes your missile network enabled (depending on what kind of DL e.g. one-way or two-way) and suitable for long range engagements (target data refresh via DL).
For the SOM missile, the guidance system comprises:
- INS / GPS
- Terrain Referenced Navigation
- Image Based Navigation
- Automatic Target Recognition
- Imaging Infrared Seeker
An
inertial navigation system (
INS) is a navigation aid that uses a computer, motion sensors (accelerometers) and rotation sensors (gyroscopes) to continuously calculate via dead reckoning the position, orientation, and velocity (direction and speed of movement) of a moving object without the need for external references
The
Global Positioning System (
GPS), originally
Navstar GPS, is a space-based radionavigation system owned by the United States government and operated by the United States Air Force. It is a global navigation satellite system that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. Other satellite navigation systems in use or various states of development include:
- GLONASS – Russia's global navigation system. Fully operational worldwide.
- Galileo – a global system being developed by the European Union and other partner countries, which began operation in 2016, and is expected to be fully deployed by 2020.
- Beidou – People's Republic of China's regional system, currently limited to Asia and the West Pacific, global coverage planned to be operational by 2020
- IRNSS - A regional navigation system developed by the Indian Space Research Organisation.
Terrain Referenced Navigation is a navigation procedure in which the current position of the aircraft is determined by means of a section of the terrain profile of the respectively overflown area, called the flight route , using a digital terrain model and made available for navigation. TRN is terrain-based navigation with
instruments. Aided by ground following radar and laser altimeter.
Automatic target recognition (ATR), is the ability for an algorithm or device to recognize targets or objects based on data obtained from sensors.
Image-based navigation aims at navigating objects by processing series of image data. These image data may be recorded with passive sensors like digital cameras or active instruments like laser scanners. Image-based navigation allows to extend the definition of navigation beyond the so far primarily geometric task.
