摘要： GPS navigation devices or GPS receivers can consume less power by using a temperature recorder circuit and/or a power manager in calculating the accuracies of the GPS system time and reference frequency to improve battery life. A representative receiver includes a time reference device that generates data associated with a GPS system time, and a temperature recorder circuit that operates using the generated data from the time reference device and monitors the temperature of the time reference device while the receiver hibernates. The receiver further includes memory including a power manager that has instructions, which are processed by a processing device after the receiver wakes up. The instructions associated with the power manager include determining if the temperature recorder circuit sent a wake-up signal, reading data from the temperature recorder circuit, and adjusting parameters associated with at least one of the following: the time reference device and the temperature recorder circuit.

摘要： Methods and apparatuses are disclosed for enabling a satellite-based navigation signal receiver to support multiple types of global navigation satellite systems (GNSS). A legacy GNSS receiver can support a plurality of GNSS types by software upgrade and with a new/modified radio frequency (RF) chip. There is no need to completely redesign a navigation host chip to support the multiple GNSS types. This invention offers a cost-efficient multi-GNSS solution without sacrificing the navigation performance. A GNSS baseband controller controls synchronization of measurement time for digitized data along a first signal processing path for a legacy GNSS signal and a second signal processing path for a non-legacy GNSS signal.

摘要： A direct sequence spread spectrum (DSSS) radio communication system of the present invention comprises a transmitter and a matching receiver. The transmitter includes a pseudorandom number (PRN) code generator, a chip clock generator and a 16.times. clock generator that runs at sixteen times the chip clock rate. The output of the PRN code generator and chip clock generator are exclusive-OR'ed to derive a Manchester encoding of the DSSS spreading code. A tri-state buffer is used to deliver such Manchester encoded DSSS spreading code to a mixer to spread a biphase shift keyed (BPSK) radio carrier before being transmitted. The tri-state buffer can be a part of the exclusive-OR logic and is connected to place its output in a high impedance state one sixteenth of every chip clock period. This provides for a suppression of the spurious sidebands that otherwise limit adjacent channel packing.

摘要： An embodiment of the present invention is a communications system for multiple users sharing the same maximal length code (MLC) in a code position modulation multiple access environment. A 1023 chip length code is transmitted with reference to an independent coordinated time source. The code repeats every time after 1023 chips have been transmitted. The MLC will begin each time period with the first through 1023.sup.rd chip, depending on the data to be sent and the identity of the user transmitting it. The chips belonging to the MLC that were not sent at the beginning of a time period are sent at the end to complete the MLC each time period in a wrap around fashion. Each time period can be arbitrarily divided into subsections embracing, for example, sixteen chip times. When so divided, more than sixty subsections are possible from one 1023 chip MLC. Respective users are each assigned a subsection. If the transmitted MLC begins on one of the sixteen chip time slots in a particular user's assigned subsection, the chip time slot that the MLC does begin on will be interpreted as communicating four bits of data, 0000 . . . 1111.
