HUT68493A - Method of and device for automatic registration of measuring data dependent on geographical place - Google Patents

Description

Geographically fixed or the collection of parameterized data was always problematic; positioning itself was the main problem. With the advent of GPS (Global Positioning System) technology, this has been resolved, and devices known as, e.g. they can record and display the distance traveled by a vehicle (ship, car, aircraft). In the case of aircraft, positioning is a three-dimensional problem; the LAT-LON (Latitude-Longitude) coordinates even require a height (LAT-LON-ALT, latitude-longitude).

A GPS satellite positioning system consists of 3 parts. These:

- satellites orbiting the earth; (currently 22 pcs.)

- Terrestrial Satellite Control Station;

- User receiver.

The satellites move on a 60 degree orbit at a fixed altitude. Their orbit is so arranged that at least 3 pieces are visible above a point (above the horizon.) At the same time, a receiver can receive signals from at least 3 satellites. The satellites measure and continuously transmit their position from their earth center and the time of transmission. The receivers receive the satellite. They determine their distance from their own satellite based on the time difference between transmission and reception.

Two-dimensional (LAT-LON) positioning requires the reception of 3 satellites and three-dimensional (LAT-LON-ALT) 4 satellites. Determining one's position is done by simple geometric analysis.

If, on the other hand, one or more additional data (measurement data) is to be recorded, then one or more additional data must be assigned to the LAT-LON value pairs (measured, recorded, exited). Examples include radioactive radiation, environmental pollution, etc.

On the application side, it is possible to meet more and more needs based on each other: these as functions:

1-Positioning (LAT-LON-ALT).

2- navigation (waypoints, bearing, heading, distance, cross trackerror, etc.), (waypoint, target bearing, machine axis, distance, page offset, etc.)

3- control (autopilot)

4-way registration and display

5- Digital Remote Transmission (for DGPS applications)

6- tracking, monitoring systems

7- measuring and evaluation systems.

Thus, the devices appearing on the market are diverse, although navigation devices are now the most widespread.

Minimum configuration of a user navigation device: a GPS receiver with antenna, a controller to render raw data suitable for navigation, and a display for display; more sophisticated instruments are already tailored to specific applications; so e.g. There are known glider aircraft instruments that already use GPS data for their optimum calculations and even record the route taken for later display. Registration is electronic, they use their own memory unit for storage, but they are stored in a similar way for other purposes, eg. as well as marine equipment.

The DGPS (Differential Global Positioning System) is capable of significantly fine-tuning the positioning of the GPS system, whereby a GPS base station sends correction data to receivers within the reception area by means of digital communication; with this app. 100 m position4

determination error can be reduced to 1-5 m. Remote transmission also plays an important role in this system.

If the registered route is shown later, eg. with the aid of a computer, then off-line, if, by means of a digital radio link, the receiving station sends its current position coordinates to a central station, then an on-line tracking system is provided.

Known devices which operate on the basis of the above have the functions described in points 1, 2 or 4 below, for example:

manufacturer type

- Cambridge (USA) L-NAV

- Zander (D)

SR 820-D

- Dittel (D)

LX2000

The following are a list of combined glider computers that feature a separate GPS receiver connected to the base instrument; Thus, they are not compact in design.

Other known instruments emphasize accuracy rather than registration (DGPS system) or real-time tracking, or a combination of the two (eg the Swedish GP & C Airport Monitoring System).

Autopilot devices (AUP), which provide automatic guidance of a moving vehicle (object), are relative in their function of maintaining a specific reference state (eg, direction, height); They have no LAT-LON connection, so they are not navigation devices.

These known devices (GPS based recording devices) have three main disadvantages:.

the. / Only the route or the route and altitude is recorded; thus their field of use is limited;

b. / The data is stored in the unit's memory, so any further evaluation of the unit can be done by connecting the unit to a computer in order to transmit data. Because of this cable connection, you need to move either the recording device or the computer, which is cumbersome.

c. / They are not compact.

d. / AUP equipment, as auxiliary equipment, is only capable of relational control (regardless of geographic position).

The device according to the invention is intended to eliminate the drawbacks. The apparatus is automatically coupled to a GPS (Global Positioning System) system for recording geolocation data, which includes an antenna that communicates with satellites, a unit that receives and registers position signals from the satellite; according to the present invention, the GPS system recording unit is supplemented with a memory card known in the art for recording and storing location signals and other received signals and messages, which can be inserted and removed from the recording unit; By loading the data stored on the memory card into a computer, using its peripherals (screen, printer, etc.), the data stored on the memory card and the results calculated from the data can be displayed.

The apparatus according to the invention:

1. / Ability to measure and record the geographical location (LAT-ION) and other measured data (such as altitude or additional measured data);

2. / Recording is done on a memory card that can be easily removed from the unit; inserted into a computer-connected reader for further processing using a suitable program.

3. / Compact design.

4. / Provides absolute AUP function; Thanks to its GPS connection, it can even follow a route with landmarks.

The apparatus according to the invention is illustrated in the accompanying drawings. Equipment shown in the drawings

c. / Measurement of environmental characteristics (eg air pollution and / or meteorological data) using a multi-channel measuring station. The analog / digital outputs of the known gauges are fed into the RPGS, sampling and recording their position and the current measured brakes on a time or distance basis. The computerized evaluation of the registered one can show the spatial distribution of each measured feature; gradients can be drawn, etc.

Current installed stations only measure at the installation site; it is advisable to obtain a detailed picture of the spatial distribution of the measured characteristics by means of a moving station rather than multiplying the number of stations.
