NMEA reporting for QZSS may be enabled/disabled by the $PMTK351 command. Satellite-Based Augmentation System (SBAS) SBAS is not supported on the current production SL871-S modules (with the enhanced ROM). The receiver is capable of using SBAS satellites as a source of both differential corrections and satellite ranging measurements. -
Page 24: Assisted Gps (Agps)
See the next section regarding EPO support (Host EPO) on the SL871-S and SL871L-S. Host EPO The SL871-S and SL871L-S do not have flash memory. However, they can still make use of Assisted GPS. If the system design includes a host processor, it can access server-generated EPO data and send it to the module over the primary serial port. -
Page 25: Static Navigation
SL871 Family Product User Guide PRODUCT FEATURES 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”. -

Page 27: Power Management Modes
SL871 Family Product User Guide PRODUCT FEATURES Power Management Modes The receiver supports operating modes that reduce overall current consumption with less frequent position fixes. Availability of GNSS signals in the operating environment will be a factor in choosing power management modes. The designer can choose a mode that provides the best trade-off of navigation performance versus power consumption. -
Page 28: Backup Mode (Perpetual) (Sl871 And Sl871L Only)
To enter the Perpetual Backup mode, use the NMEA command: $PMTK225,4. Only the SL871 and SL871L have a Force_On pin. This command will be rejected on the other modules (SL871-S and SL871L-S). To exit the Perpetual Backup mode, bring the Force_On signal high, then return to low. -
Page 29: Periodic Modes (Sl871 And Ls871L Only)
SL871 Family Product User Guide PRODUCT FEATURES Periodic Modes (SL871 and LS871L only) These modes allow autonomous power on/off control with reduced fix rate to decrease average power consumption. The main power supply pin VCC_ON is still powered, but power distribution to internal circuits is internally controlled by the receiver. -
Page 30: Alwayslocate™ Modes
AlwaysLocate™ Modes (Not available on the SL871L-S and current production SL871-S with enhanced ROM) AlwaysLocate™ is an intelligent controller of the Periodic mode where the main supply pin VCC_IN is still powered, but power distribution is controlled internally. Depending on the environment and motion conditions, the module can autonomously and adaptively adjust the parameters of the Periodic mode, e.g. -
Page 31: Data Retention
SL871 Family Product User Guide DATA RETENTION 5 DATA RETENTION (SL871 and SL871L modules only) The receiver is capable of retaining data elements under the various initialization types. If Vbatt is maintained, no data will be lost. The following table shows which data elements are saved under each type of initialization if both Vcc and Vbatt are removed. -

Page 55: Antenna Rf Interface
RF-IN The RF input (RF-IN) pin accepts GNSS signals in the range of 1561 MHz to 1606 MHz (1573.42 to 1577.42 MHz for the SL871-S) at a level between -125 dBm and -165 dBm into 50 Ohm impedance. The RF input pin is ESD sensitive. -
Page 56: 10 Rf Front-End Design
RF FRONT-END DESIGN 10 RF FRONT-END DESIGN The SL871 and SL871-S modules contain a preselect SAW filter in front of the RF input. The SL871L and SL871L-S modules add an LNA in front of the (post-select) SAW filter which allows the modules to work well with passive GNSS antennas. -
Page 57: Gnss Antenna Polarization
SL871 Family Product User Guide RF FRONT-END DESIGN blockage caused by buildings, terrain or other objects near the line of sight to each specific GNSS satellite. This variable attenuation is highly dependent upon satellite location. If enough satellites are blocked, say at a lower elevation, or all in one general direction, the geometry of the remaining satellites will be worse (higher DOP) and will result in a lower position accuracy. -
Page 58: Gnss Antenna Gain
SL871 Family Product User Guide RF FRONT-END DESIGN GNSS Antenna Gain Antenna gain is defined as the amplified signal power from the antenna compared to a theoretical isotropic antenna (equally sensitive in all directions). For example, a 25 mm by 25 mm square patch antenna on a reference ground plane (usually 70 mm by 70 mm) may give an antenna gain at zenith of 5 dBic. -
Page 59: Rf Trace Losses
SL871 Family Product User Guide RF FRONT-END DESIGN RF Trace Losses RF Trace losses on a PCB are difficult to estimate without having appropriate tables or RF simulation software. A good rule of thumb would be to keep the RF traces as short as possible, make sure they are 50 ohm impedance and don’t contain any sharp bends. -

(SL8721 Gen 2 and SL871-S only) The SL871 and SL871-S modules include a pre-select SAW filter at the RF input in front of the internal LNA. Thus, the RF input of the module is connected directly to the SAW filter. Any... -
