Abstract: The invention relates to a method for determining the phase of information modulated in a code-modulated signal transmitted by a satellite in a receiver (MS). In the method, at least partly the same information is transmitted from at least a first and a second satellite (SV1-SV4) substantially simultaneously, the code-modulated signal transmitted from at least the first and the second satellite (SV1-SV4) is received, and at least the received signal of the first satellite is demodulated to determine the transmitted information.

Abstract: The invention relates to a method for acquiring a receiver (1) into a code modulated spread spectrum signal received by the receiver (1). In the method at least one replica code (r) is used which corresponds to a code used with the modulation having a pre-determined number of chips, and an examination phase is performed, in which a frequency shift of the signal within a selected frequency area is examined, and a code phase of the code used with the modulation is examined. In the method the frequency shift examination is divided into a first estimation phase and a second estimation phase, wherein in the first estimation phase the selected frequency area is divided into a first set of frequencies, and in the second estimation phase a second set of frequencies is examined nearby each frequency of the first set of frequencies.

Abstract: The invention relates to a method for positioning a receiver (MS) in positioning means (S, MS). In the method, a code modulated signal transmitted by satellites (SV1-SV4) and formed by an individual code for each satellite (SV1-SV4) is received. In the method, at least one reference point (BS) is selected, whose position is substantially known, In the method, information is transmitted to the positioning means (S, MS) about the position of said at least one reference point, and about Ephemeris data on the satellites (SV1-SV4). Thus, at least the Ephemeris data on each of the satellites (SV1-SV4) to be used in the positioning and the location of said at least one reference point are used in the positioning of the receiver.

Abstract: The invention relates to a navigation method, in particular for vehicles, in which a route (R) from a starting point (z1) to a destination (zn) is determined and stored, in which the current position (z(t)) is determined, and in which direction information corresponding to the route (R) is indicated. In order to allow the user to be guided to his destination, if he leaves the route, without using map material, the invention provides for a direction which leads back to the route to be indicated, if the current position is not on the route.

Abstract: The invention introduces an arrangement which maintains the usefulness of a fader control (11) connected for example to an audio signal source (10), and at the same time considerably reduces the circuit cost. This is realized in that the distribution to different listening areas adjusted by the fader control (11) is determined from the audio signals that are present behind the fader control (11). To that end, first the audio output signals (L, R) are reconstructed in two adders (12.2, 12.3) and routed to a fourth adder (12.4). Two each audio signals (L.sub.V, R.sub.V) are routed to a first adder (12.1). The signals existing behind the adders (12.1/4) are then placed into a ratio with each other by a divider (20). From the quotient Q determined there, the distribution rate is then determined by a calculator (21) and made available to the multipliers (M1-4). Devices (17) to determine the average level value, followed by smoothing devices (18), which are positioned symmetrically with respect to the adders (12.
