 Both the Pysense and Pytrack use the same accelerometer. Please see the [Pysense Examples](pysense.md) to see how to use the accelerometer.

+## Example
+
+You can find this example in the [pycom/pycom-libraries](https://github.com/pycom/pycom-libraries) GitHub repository.
+
+```python
+import machine
+import math
+import network
+import os
+import time
+import utime
+import gc
+from machine import RTC
+from machine import SD
+from L76GNSS import L76GNSS
+from pytrack import Pytrack
+
+time.sleep(2)
+gc.enable()
+
+# setup rtc
+rtc = machine.RTC()
+rtc.ntp_sync("pool.ntp.org")
+utime.sleep_ms(750)
+print('\nRTC Set from NTP to UTC:', rtc.now())
+utime.timezone(7200)
+print('Adjusted from UTC to EST timezone', utime.localtime(), '\n')
+
+py = Pytrack()
+l76 = L76GNSS(py, timeout=30)
+
+# sd = SD()
+# os.mount(sd, '/sd')
+# f = open('/sd/gps-record.txt', 'w')
+
+while (True):
+    coord = l76.coordinates()
+    #f.write("{} - {}\n".format(coord, rtc.now()))
+    print("{} - {} - {}".format(coord, rtc.now(), gc.mem_free()))
+```
