| 2 | + Reading lat, long and UTC time via UBX binary commands - no more NMEA parsing! |

| 8 | + License: MIT. See license file for more information but you can |
| 9 | + basically do whatever you want with this code. |
| 10 | +
|
| 11 | + This example shows how to query a Ublox module for its lat/long/altitude. We also |
| 12 | + turn off the NMEA output on the I2C port. This decreases the amount of I2C traffic |
| 13 | + dramatically. |
| 14 | +
|
| 15 | + Note: Long/lat are large numbers because they are * 10^7. To convert lat/long |
| 16 | + to something google maps understands simply divide the numbers by 10,000,000. We |
| 17 | + do this so that we don't have to use floating point numbers. |
| 18 | +
|
| 19 | + Leave NMEA parsing behind. Now you can simply ask the module for the datums you want! |
