  • Page 23: Static Navigation

    SL869x-V2 Family Product User Guide Static Navigation Static Navigation is an operating mode in which the receiver will freeze the position fix when the speed falls below a set threshold (indicating that the receiver is stationary). The course and altitude are also frozen, and the speed is reported as “0”. The navigation solution is unfrozen when the speed increases above a threshold or when the computed position exceeds a set distance (10 m) from the frozen position (indicating that the receiver is again in motion).

    SL869x-V2 Family Product User Guide Internal LNA (SL869L-V2 and SL869L-V2S only) The SL869L-V2 and SL869L-V2S modules include a built-in LNA to increase sensitivity. 1PPS The module provides a 1PPS output signal. Please refer to Section 9.3.5.1 1PPS for detailed information. Power Management Modes The receiver supports operating modes that reduce overall current consumption with less frequent position fixes.

  • Page 25: Standby Modes

    SL869x-V2 Family Product User Guide The receiver switches to the tracking engine to lower the power consumption when: • A valid GPS/GNSS position is obtained. • The ephemeris for each satellite in view is valid. To return to Full Power mode from a low power mode, send a $PMTK225,0*2B command just after the module wakes up from its previous sleep cycle.

  • Page 57: Rf Front End Design

    SL869x-V2 Family Product User Guide 10. RF FRONT END DESIGN The SL869-V2 and SL869-V2S modules contain a preselect SAW filter in front of the RF input. The SL869L-V2 and SL869L-V2S modules add an LNA in front of the (post-select) SAW filter which allows the modules to work well with passive GNSS antennas. For improved performance, or if the antenna cannot be located near the receiver, an active antenna (that is, an antenna with a built-in low noise amplifier) can be used.

  • Page 58: Gnss Antenna Polarization

    SL869x-V2 Family Product User Guide • Partial or total path blockage (such as foliage or buildings) • Multipath interference (caused by signal reflection) • GNSS antenna characteristics • Signal path after the GNSS antenna The GNSS signal is relatively immune to attenuation from rainfall. However, it is heavily influenced by attenuation due to foliage (such as tree canopies, etc.) as well as outright blockage caused by buildings, terrain or other objects near the line of sight to each specific GNSS satellite.

  • Page 59: Active Versus Passive Antenna

    SL869x-V2 Family Product User Guide If the multipath signal is attenuating the line of sight signal, then the RHCP antenna would show a higher signal level than a linearly polarized antenna because the interfering signal is rejected. However, in the case where the multipath signal is replacing the line of sight signal, such as in an urban canyon environment, then the number of satellites in view could drop below the minimum needed to determine a 3D position.

  • Page 64: Shielding

    SL869x-V2 Family Product User Guide Shielding Shielding the RF circuitry generally is ineffective because the interference is received by the GNSS antenna itself, the most sensitive portion of the RF path. The antenna cannot be shielded because then it could not receive the GNSS signals. There are two solutions, one is to move the antenna away from the source of interference, and the other is to shield the digital interference source to prevent it from getting to the antenna.

    SL869x-V2 Family Product User Guide When re-flowing a dual-sided SMT board, it is important to reflow the side containing the module last. This prevents heavier components within the module from becoming dislodged if the solder reaches liquidus temperature while the module is inverted. https://www.jedec.org Note: JEDEC standards are available free from the JEDEC website The recommended reflow profile is shown in the following figure:...
