Neer Tide is Nano, compact, handy and versatile easy to operate and simple to install radar-based tide gauge recorder for hassle free and accurate monitoring and recording of the tidal data. Neer Tide can be essentially used by ports and Harbour authorities, survey agencies, educational institutes and environmental agencies for various applications for tide monitoring.

Neer Tide is made up of components designed to withstand the marine environment and housed in ruggedized water proof case making it extremely portable. Neer Tide does not have any submerged sensors or moving parts in water thereby reducing the maintenance required. It can be used for permanent installation for port operations or can be used as a portable tide recorder for short term use. Neer Tide uses state of art technology and can be used as standalone system or as apart of integrated network of tide gauges.

Around the world we are seeing dramatic increases in demands on shipping. Ships are getting Bigger, and although new ports are being built to cope with them, many existing ports have little scope to expand. This means:

• • Tighter manoeuvring margins
• • Increased stress and demand on the bridge-team
• • Increased stress on pilots
• • Greater scope for error

When pilots guide vessels into busy tide-bound ports, precise navigation is essential. Minimizing under-keel clearance maximizes profit, especially if the vessel can enter and exit port earlier than normal. Accurate navigation is also vital in avoiding multi-million-dollar damage to one’s own vessel, to other vessels, and to port infrastructure.

Absolute precision is required in terms of horizontal and vertical positioning, bow and stern speed, heading, and rate of turn. Although historically pilots have relied almost exclusively on their own knowledge, experience and intuition, advances in technology are now available to assist them. Adoption of technology is generally very slow, often because ports have difficulty seeing the benefits that technology can bring. The benefits can vary from port to port, but one example is of a port in which, in one use of such an equipment, saved its purchase price several times over by simply being able to sail a ship which would otherwise have blocked berth until the next tide.

DevNav Lite PPU is a simple position only system which through its technological options shows the level to which each can assist pilots and ports in improving safety and profitability. It’s the simplest electronic aid is one that uses a single GPS receiver. The system typically comprises a laptop and a single antenna, integrated into the display with a cable connection to a laptop and AIS using pilot plug.

Every SOLAS compliant ship carries an AIS onboard and every type approved AIS has a pilot plug on it. The AIS onboard is connected to the ship’s GPS, gyro and Log. Thus, the AIS is an excellent single point source for all the data required for pilotage. The pilot connects with matching pilot plug to this AIS’s pilot plug and connects his laptop to the AIS for receiving all the data required. The laptop runs a special pilotage software VINAM and has an accurate chart of the area DevNav Lite is an inexpensive and very portable – and may be all that is required in relatively straight and wide channels. For example, it shows the position of the vessel, (where the antenna is sited) in relation to its surroundings and other vessels, which can help prevent confusion as to which buoy or vessel the ship is passing.

As ships move into more restricted waters, the need for DevNav Pro becomes more effective. The size of the ship in relation to the navigable water becomes significant, and it is critical that the ship’s outline is accurately displayed on the chart. While this can be achieved in some software by entering the ship’s dimensions, together with the offsets of the GPS antenna, the displayed picture is only meaningful if heading is accurate. Simple systems can only assume that ship’s head is the same as the course over ground (COG) while this is a valid assumption when the ship is moving in a straight line with no wind or tidal stream, heading will be gravely in error once the ship starts to turn. At slow speeds, and particularly when using tugs or moving astern, ship’s head and COG may be up to 180º apart. For precise navigation in confined waters it is vital to know heading, as this allows every part of the ship to be shown in its correct position on the chart.

There are two main ways of obtaining heading and ROT for use on a portable system:
AIS, and Portable Pilot Units with their own heading sensors. DevNav Pro PPU is an Advanced (position and heading) systems which uses its own heading sensors providing the pilot accurate and separate navigation information independent from the ship sensors it can also integrate its own AIS sensor or the AIS information through the pilot plug thus assisting the pilots and ports in improving safety and profitability.

It’s a state-of-the-art electronic aid that uses a dual channel DGPS receiver and has its own independent heading sensor.

The system typically comprises a laptop and a dual antenna, integrated into the display with a cable connection to a laptop and AIS using pilot plug the pilot connects with matching pilot plug to this AIS’s pilot plug and connects his laptop to the AIS for receiving all the data required. The laptop runs a special pilotage software VINAM and has an accurate chart of the area DevNav Pro is a state of the art very portable – and may be all that is required by the pilot even in more restrictive and challenging ports. For example, it shows the independent speed of the bow and the stern during berthing thereby giving the pilot true alignment of the vessel in relation to the berth and also in relation to its surroundings and other vessels.

Traditionally, navigational aids (also known as “aids to navigation”, or ATON) have been physical aids such as lighthouses, buoys, and beacons. However, AIS Virtual AtoN is navigation system where no physical object or structure is associated with the navigational aid.

AIS Virtual AtoN provides for the ability to send addressed messages to a specific wheelhouse (by addressing the message to the unique MMSID assigned to the AIS transponder on the vessel). AIS safety-related messages can also be broadcasted to all vessels within range of the broadcasting base station.

Some of the benefits of an AIS Virtual AtoN are:

• • Physical inventory of buoys and other monitoring devices to not have to be purchased, deployed, and maintained in the water.
• • An AIS base station can serve an extended geographical region – often in excess of 50 square miles per station.
• • Since the AIS base station is typically deployed in a fixed location on land (or on an offshore platform), acquisition and maintenance costs are typically lower than physical ATONs.

We provide complete range of navigation buoys with Aton's systems. Our extensive range includes lanterns, AIS systems, battery and solar powered solutions. With our expertise, we provide end-to-end solutions. We can also offer installation and commissioning and servicing and maintenance for all types of Navigation Bouys.

We can provide fully qualified and certified engineers for on-site installation and commissioning for all types of aids to navigation systems and its maintenance, includes:

• • Navigation Buoys
• • Beacon Towers
• • Solar power lantern systems
• • Mains power lantern systems

Vessel Identification Navigation And Monitoring (VINAM) is an AIS based Vessel Traffic Management System. It is designed for the aid of the mariners and the managers. VINAM is capable of identifying & managing vessel traffic from a control room ashore or onshore. VINAM is a Windows based system usable on all commercial PC’s or laptops operating under Window XP.

VINAM can be tailor made for covering of all vessel traffic and navigation requirements of the user in his area of interest. VINAM is a user friendly and easy to use software developed keeping in mind the end user requirements.
