Adafruit Ultimate GPS Module - 66 channel w/10 Hz updates - PA1616S

Key Features: -165 dBm sensitivity, 10 Hz updates, 66 channels Ultra low power usage: 20mA current draw while tracking 3.3V operation, RTC battery-compatible Just the GPS module itself, no breakout board or other components included For those who want to integrate our awesome Ultimate GPS module into their own projects, we now have the raw sub-module available. Don't be fooled by it's small size, this is a very sensitive, high quality GPS module with all the extras you could want and more at under 6 grams!This module is built around the MTK3339 chipset, a no-nonsense, high-quality GPS module that can track up to 22 satellites on 66 channels, has an excellent high-sensitivity receiver (-165 dB tracking!), and a built in antenna. It can do up to 10 location updates a second for high speed, high sensitivity logging or tracking. Power usage is incredibly low, only 20 mA during navigation.Two features that really stand out about version 3 MTK3339-based module is the external antenna functionality and the the built in data-logging capability. The module has a standard ceramic patch antenna that gives it -165 dB sensitivity, but when you want to have a bigger antenna, you can attach an active antenna to the ANT pad. The module will automatically detect the active antenna and switch over!Item SpecificsSatellites: 22 tracking, 66 searchingPatch Antenna Size: 15mm x 15mm x 4mmUpdate rate: 1 to 10 HzPosition Accuracy: < 3 meters (all GPS technology has about 3m accuracy)Velocity Accuracy: 0.1 meters/sWarm/cold start: 34 secondsAcquisition sensitivity: -145 dBmTracking sensitivity: -165 dBmMaximum Velocity: 515m/sVin range: 3.0-5.5VDCMTK3339 Operating current: 25mA tracking, 20 mA current draw during navigationOutput: NMEA 0183, 9600 baud default, 3V logic level out, 5V-safe inputDGPS/WAAS/EGNOS supportedFCC E911 compliance and AGPS support (Offline mode : EPO valid up to 14 days )Up to 210 PRN channelsJammer detection and reductionMulti-path detection and compensationNote: Original Ultimate GPS chip discontinued in late 2022.
