Using Marine Traffic (AIS) to make stock picks?
Does MarineTraffic use AIS?
The system is based on the collection and processing of data transmitted via the AIS (Automatic Identification System). The AIS-Receiving stations that comprise the MarineTraffic network pick-up such data and share it with the MarineTraffic central database.
Is MarineTraffic accurate?
To provide users with accurate and actionable data, MarineTraffic uses real-time filtering and analysis combined with post-processing. The chaotic raw data flow is filtered down to 30 million positions each day: one position per ship, per minute.
Is MarineTraffic API free?
Marine Traffic publishes API to track ships and ports activity. It is a paid service, with a pay-per-use pricing.
How does MarineTraffic app work?

Quote: Point your phone in nearby vessels to identify them at a glance plan your route calculate distance and trip duration. Directly on the map.
How accurate is AIS data?
Overall, it was revealed that the mean discrepancy between AIS and radar data measures about 97.72m. Moreover, some presented approaches can approximate AIS data with higher accuracy than the classical linear interpolation.
What frequency does AIS transmit on?
AIS transponders and receivers use two VHF radio frequencies: 161.975 MHz (AIS1, or channel 87B) and 162.025 MHz (AIS2, or channel 88B). The USCG has asked the Federal Communications Commission to authorize any US vessel to operate AIS on these two channels under its existing ship station license.
What is the best ship tracking app?
myshiptracking
With its large database, myshiptracking allows users to monitor vessels and ports efficiently to analyze the marine traffic across the world. The website also allows you to save your browsing data and offers its service to iPhone and Android users through mobile apps.
How do you use AIS?
Just place the chart plotter’s cursor on an AIS icon, and a list of valuable information unfolds. The ship’s name and radio call sign are shown. This means you can pick up a VHF and hail a specific vessel that may be posing a threat.
What is ETA in MarineTraffic?
Calculated ETA is a more regularly updated prediction of the arrival at the destination based upon AIS-reported details (speed, course, reported destination), past voyages and shipping lanes. This is a dynamic process provided by MarineTraffic based on data-driven information and calculations.
How much is the MarineTraffic app?
We understand that you would like to track multiple vessels through our services, but you have faced an issue with our pricing. First and foremost, please allow us to clarify that our app costs 4.99$. It is a paid as it does not contain ads, and it has been designed to offer certain of our features on the go.
How do I get data from AIS?
To receive all AIS transmissions a receiver must monitor both channels simultaneously, so the receiver must in effect be two receivers in one box. If two separate and different transmissions arrive at the receiver at the same time but on different channels both transmissions will be received and output by the receiver.
How is AIS data collected?
Global AIS transceiver data collected from both satellite and internet-connected shore-based stations are aggregated and made available on the internet through a number of service providers.
What are the 3 dynamic information of an AIS?
AIS transmits, automatically and at set intervals, dynamic information relating to the ship’s course, speed and heading; static information related to the ship’s name, length, breadth; and voyage-related details such as cargo information and navigational status (e.g. underway or at anchor).
What are the main limitations of AIS?
Limitations of AIS
- The accuracy of AIS information received is only as good as the accuracy of the AIS information transmitted.
- The position received on the AIS display might not be referenced to the WGS 84 datum.
- Over-reliance on the AIS can cause complacency on the part of the OOW.
What is the difference between Class A and Class B AIS?
Class A AIS transponders are required to have a DSC (156.525 MHz) receiver, external GPS, heading, and rate of turn indicator, and can also transmit and receive safety-related text messages. Class B AIS transponders operate using Carrier-Sense TDMA (CSTDMA) broadcast mode and transmit at a power level of 2 watts.
Why do ships turn off AIS?
A ship’s crew may turn off its AIS broadcast for a variety of legitimate reasons, but this behavior may indicate that a vessel is hiding its location and identity to conceal illegal activities like fishing in no-take protected areas or entering another country’s waters without authorization.
Do I need VHF with AIS?
AIS works via a combination of GPS, VHF radio, and an AIS transponder. The transponder broadcasts a ship’s information, such as speed and heading (information gathered by GPS, of course), the ship’s name, port of origin, size and draft, and more, over VHF frequencies 161.975 megahertz and 162.025 MHz.
How many types of AIS are there?
Types of AIS equipment.
For a shipboard fitting there are three types of AIS equipment, Class A, Class B and receive only. Class A is intended for vessels where the fit is mandatory. Class A transmits more information, more frequently and at higher power than Class B.
Do Naval Vessels use AIS?
AIS is a key maritime safety system used to track vessel movements. Nearly 100 naval ships may have had their AIS position altered, environmental groups SkyTruth and Global Fishing Watch found. The ships included vessels from European and US navies, including 11 from the Royal Navy.
What vessels are required for AIS?
Regulations for carriage of AIS
The regulation requires AIS to be fitted aboard all ships of 300 gross tonnage and upwards engaged on international voyages, cargo ships of 500 gross tonnage and upwards not engaged on international voyages and all passenger ships irrespective of size.
