Definitions
- GPS receivers specified for different start modes A distinction is made between warm and cold start. During a cold start, there are no current system data and operating parameters in the receiver, or the data is out of date and may no longer be correct with the actual ones System data or operating parameters match. Due to the lack of information, the visible or inexpensive satellites cannot be determined in the receiver, which is why the receiver is dependent on trying out individual ones of the 32 satellites provided in the GPS system specification.
- the receiver is initialized according to the number of channels available in parallel with so-called search sets, which enable a more or less orderly search of the satellites. It is known to use 8 different satellite identifiers for an eight-channel receiver per search set. The satellite IDs listed as PRN numbers are searched in order. Depending on the position of the receiver, this can take a long time before a satellite is found that is available for communication.
- Satellites are in an orbit, the plane of which is inclined at 60 ° to the equatorial plane.
- the angle between the individual levels is also 60 ° and is plotted over the R axis.
- the individual satellites can be identified in the receiver by their different PRN codes.
- the PRN numbers For the cold start according to the method according to the invention, one selects from the PRN numbers for the search sets levels which are as perpendicular as possible to one another and thereby all satellites of this level. So, even without knowing the initial position, you have the greatest possible probability of receiving at least one visible satellite of this set at any point on earth.
- the first search set could e.g. B. from level C and A satellites, the second search set from the level B and D satellites and the third search set from the level E and F satellites.
- Eight-channel receiver consists of eight PRN numbers from possible satellite transmitters, the search 5 begins for a satellite that is visible to the receiver. As soon as the receiver has received the signal from the first satellite, it begins to query the current almanac data 6.
- the almanac -Data contain all current orbit and operating parameters of the active satellites.
- the first active satellite transmits five data frames to the receiver, of which the first three data frames contain information about position, absolute time, etc.
- the almanac is transmitted in the fourth data frame.
- the information about the individual satellites is transmitted in five subframes, the transmission rate being 50 bauds.
- the transmission of the data for a total of 32 possible satellite identifications, of which, as a rule, 24 according to the system specification
- Satellite IDs assigned to the active satellites take a maximum of 12.5 minutes. From the almanac, the receiver then calculates the current occupancy of the various orbital planes by the satellites and generates the list of valid search sets 7 using the method according to the invention.
