When the beam reflects off a moving object, a measurable frequency shift occurs which is then converted into miles per hour to determine the objects speed.,11,Type of Radars,I.Doppler Radar Based on Doppler effect, used for measuring wind direction and wind speed,12,Type of Radars,II.Bistatic RadarHelpful in creating 3D image of the target It has a normal monostatic Radar which transmits a narrow beam and receives the backscattered radiation, at the same time one or more passive bistatic receivers recover some of the other scattered radiations, giving multiple angles from which the signal is coming form, this helps in creating 3d image of the target.,13,AIS,The Automatic Identification System (AIS) is designed for improving safety and efficiency of navigation in the open sea and coastal waters through the automatic exchange of navigational, statistic and voyage information between the ships and coastal stations.,Functions of AIS,Static DATA,Dynamic DATA,Voyage Related DATA,Safety MSG,Functional MSG,AIS,15,How AIS Work?,A Broadcast system that acts like a transponder, operating in the VHF maritime band, that is capable of handling well over 4,500 reports per minute and updates as often as every two seconds. It usesSelf-Organizing Time Division Multiple Access (SOTDMA) technology to meet this high broadcast rate and ensure reliable ship-to-ship cooperation.,16,Components of AIS?,AIS consists of :VHF TransceiverDisplay and Sensor SystemGPS/DGPSInterface with VTS,17,Communication links,To establish link between different VTS stations. Required for transfer of VTS related data from Remote Sensor site to Master control station and vice versa.Can be Microwave Or Optical fiber linkFor communicating with a vessel entering VTS area a separate VHF channel is used.,18,Radio Direction Finder,An instrument that can determine the direction that a radio transmission is coming from. The RDF is used to find the direction of a radio is coming form, to help determine the vessels position,19,How it works?,Radio Direction Finder work by pointing a directional antenna in various directions and then listening for the direction in which the signal came through most strongly,20,Meteorological Equipments,Meteorological Sensors: Wind speed and Direction VisibilityHumidityAir pressureRainfallAir TemperatureInterfacing with VTS,21,Hydrographic Equipments,Hydrographic SensorsCurrent (stream) speed and directionWave HeightWater Level,22,Future of VTS,VTS will play more important role for the overall safety measures not only in a regional geographical area but also in the globe by sharing data obtained by each regional/local VTS between the different VTS systemsThe information available to VTS could be used for further application and can be used by various other agencies,VTS GOK PROJECT,24,Goal of project,To provide seamless surveillance of entire GOK for Radar targets of RCS of 50 Sqr. Meter measured at 3 m height.,25,Overview of project,Project is divided in three major partConstruction of 9 (60 m) RCC + 1(60) RCC (to be made by other authorities), 1 (50m) RCC, 1 (30m) RCC, 1 (55m) steel lattice, 1 (30m) steel lattice, 2 roof top towers and other buildings at different sites - By M/s M L DalmiyaEstablishment of 16 E1 (7 GHz band) Microwave links and optical fiber link between Kandla MCC, Radar and Port Monitor Stations. - By TCILIII.Surveillance of traffic in the GOK with the help of Radar and other Equipments.-By HITT,Implementation Schedule,Mar May Jul Sep Nov Jan Mar May Jul Sep Nov Jan Mar May,2005 20062007,Civil Works,Telecom Works,VTS Works,KOTESHWAR,CHUDESHWAR,KANDLA,BHADRESHWAR,NAVINAL,MANDAVI,CHACHHI,VANKU,JAKHAU,HARUDI,VADINAR,SIKKA,BALCHADI,ROZI BUNDER,NAVLAKHI,OKHA,29,Description of VTS- GOK Project,There are 9 Radar stations (RS), 6 Port Monitor Stations (PMS), 1 Master Control Center (MCC), a total of 15 hops 7 GHZ MW links in tandem and spur which includes 3 MW repeater stations and 5 OFC links. Master control center : Central controlling unit of VTS- GOK project.Port monitoring station: For catering the needs of different ports in the GOK areaApart from this project also cater other users namely Coast Guard and Indian Navy,KOTESHWAR,JAKAHU,CHACHHI,MANDVI,NAVINAL,BALACHADI,CHUDESHWAR,OKHA,MCC,KANDLA,VADINAR,NAVLAKI PMS,ROZY BUNDER PMS,SIKKA PMS,HARUDI,VANKU,BHADRESHWAR,OKHACG,OKHAINS,JAKAHUCG,VHF Link,Microwave Link (15),OFC Link (5),Radar Station (9),MCC (1),PM Station (6),MW Repeater station (3),Vessel,Coast Guard and Indian Navy Stations,VTS COMMUNICTION SYSTEM IN GULF OF KACHCHH,OKHA,KANDLA PMS,31,Importance MW link,All Radar Stations and Port Monitoring Stations are linked to the Master Control Center at Kandla.Information from MCC flow back to PMS and Radar stationsc)Master control center at Kandla, all 9 Radar videos will be available through digital microwave link. d)Radio direction finder at Okha and Jakahu will be linked to MCC through a Microwave link.e)AIS data will be integrated with tracked data of Radar and will be available at MCC.,32,Locations of sites VTS-GOK Project,Port Monitoring Stations (PMS) are located at:Okha, Sikka,Vadinar, Navlakhi, Rozi Bunder and KandlaRadar stations (RS) are located at:Koteshwar, Chachhi, Mandvi, Navinal, Balachadi, chudeshwar, Okha Jakhau and KandlaRepeater Stations are located at:Bhadreshwar, Harudi and Vanku,33,I. 9 X Band and 2 S Ba
