TimeCaster - SpaceQuest

TimeCaster - SpaceQuest, Maerospace Corporation

The GeoService TimeCaster™ - SpaceQuest is a unique solution making AIS data from Spacequest more useful. Simply feed into your maritime awareness application the TimeCaster™ message queue.

The TimeCaster™ big data analytics gives estimates on ship positions even when the last received satellite AIS signal is some time ago. It reduces ambiguities, shows the vessel’s tracks and forecasts routes and arrival times.

Our flexible pricing scheme with low entry packages and flat rates makes the service affordable for businesses of any size. You can maximize the flexibility by booking monthly or minimize costs by purchasing an annual subscription.

If you need historical data sets, choose our unique Global AIS Archive.

Your benefits

Product description 

Based on raw AIS data the TimeCaster™ service predicts the current and future positions of all ships globally as of a common time (“now” or in the near future).

  • Improved accuracy:
    TimeCaster™ improves accuracy of the actual and predicted ship positions by 4- to 14-fold compared to raw satellite and terrestrial AIS data. Raw AIS data position errors range from 75 - 160 nmi, while TimeCaster™ increases the accuracy to 10-30 nmi through the predictive analytics algorithms.
  • 10-Minute position updates on all ships globally:
    The service updates every ship position every 10 minutes. Other technologies only provide positions with an average age of 2+ hours and with age spreads ranging 10 minutes to more than 24 hours. TimeCaster™ also predicts all ship positions several hours into the future.
  • Less ambiguous:
    The service automatically detects, tracks and predicts locations for Doppelgangers. Doppelgangers present a significant issue: 9,000+ MMSI’s (i.e. ship identity numbers) are used by more than one ship every day. The existence of a Doppelganger can cause a ship to disappear from a display, makes the static (e.g. name, IMO number) and voyage (e.g. destination) data ambiguous and makes track histories unreliable.
  • Easy to integrate:
    TimeCaster™ provides a data stream that can directly feed your existing display and analytics systems. It supports NMEA4, OTH-Gold or customized data interface standards.
