Real-time GPS
This form of GPS data logging performs differential correction of information as the receiver moves to create a map.
Real-time form data validation: Form data such as user IDs, serial numbers, postal codes, or even special coupon codes that require server-side validation can be validated in a form before the user submits a form.
Real-Time Location Display
If you travel with a GPS unit and laptop PC, USAPhotoMaps can display your real-time track on a photo or topo map as you move.
Real-time DGPS
The US Coast Guard operates a series of DGPS base stations at various coastal positions in the USA.
Real-time: Computations or data communications that occur instantaneously or nearly so with the execution of a command or transaction.
[edit] Real-time databases
A real-time database is a processing system designed to handle workloads whose state is constantly changing. This differs from traditional databases containing persistent data, mostly unaffected by time.
Real-time modeling
Your SCADA provides real-time data from your infrastructure in the field.
Real-time map browsers provide access to very large spatial databases and allow users to browse, display, query, retrieve, and update maps on line. Real-time browsing requires a powerful spatial data server and clients.
Real-time differential GPS
A base station which computes, formats, and transmits corrections usually through some sort of data link (e.g. VHF radio or cellular telephone) with each new GPS observation.
Real-time processing:
Internal or external processor (a PC with dual communication ports)
Minimum 4800 baud radio/modem data-link set
Postprocessing:
L1/L2 GPS receiver
386/486 PC ...

real-time Refers generally to systems that respond (almost) immediately or synchronously to external events.
Delivery Services: Message couriers and package and cargo transportation companies will also benefit from better real-time tracking and management of assets.
Space flight increased knowledge of the rest of the universe and allowed for global real-time communications via geosynchronous satellites.
Obviously, at the other extreme metsats can provide near real-time indications of weather conditions that portend severe storms and heavy rainfall.
A low resolution surface or wire grid (optional) provides real-time viewer positioning capabilities. Similarly, a lighting "model" provides real-time feedback as the user adjusts lighting.
The largest activity currently under way is the development of base map data, digital orthophotos, and ele vation models for all Energy Systems facilities using advanced stereo photogrammetric techniques based on real-time airborne GPS.
Video mapping systems still exist, and they're important to those who require a link between maps and real-time video.
[ESRI software] One of two methods for displaying temporal data in ArcGIS Tracking Analyst: real-time mode or playback mode. Time modes are determined by the use of the Tracking Analyst Playback Manager.

Blue Logger offers the dual functions of real-time location tracking when used with DeLorme mapping software on either a PC or PDA, and standalone data collection based on parameters established using the Blue Logger manager software.
Finally, tracking is a process of collecting attribute data on changes that occur at a location over a period of time. Examples of tracking include: monitoring the change of an ecosystem, and real-time monitoring of a moving objects such as ...

Fast, trivial equations led to its resurgence in rough computer-drawn maps, with early machines or real-time graphics. It is still commonly used in digitized textures ("skins") of earthly and planetary features.
The use of these tools continues to increase among individuals and organizations. While the convenience and real-time communication has made these tools very popular, there are potential security risks that all users must understand.
This corrected information is then transmitted to other GPS receivers in the area. The resulting real-time accuracy is in the S-to 10-meter range.
