A porting of a GPS decoding and presenting program within the mbos RTOS. It is not a definitive application but a study program to test NMEA full decoding library and a first approach to an RTOS. Many thanks to Andrew Levido for his support and his patience on teaching me the RTOS principles from the other side of the Earth. It uses NMEA library by Tim (xtimor@gmail.com) ported by Ken Todotani (http://mbed.org/users/todotani/) on public mbed library (http://mbed.org/users/todotani/programs/GPS_nmeaLib/5yo4h) also available, as original universal C library, on http://nmea.sourceforge.net

| guiott | 0:d177c0087d1f | 13 | control navigation of a robot in an outdoor environment. |

| guiott | 0:d177c0087d1f | 15 | This version is developed within the mbos RTOS: |

| guiott | 0:d177c0087d1f | 18 | It uses NMEA library by Tim (xtimor@gmail.com) |
| guiott | 0:d177c0087d1f | 19 | available on public mbed library or http://nmea.sourceforge.net |
| guiott | 0:d177c0087d1f | 20 | |
| guiott | 0:d177c0087d1f | 21 | The original gmath.c has been modified to fix a bug in nmea_distance_ellipsoid() function |
| guiott | 0:d177c0087d1f | 22 | according to bug report ID: 2945855 |
| guiott | 0:d177c0087d1f | 23 | |
| guiott | 0:d177c0087d1f | 24 | http://sourceforge.net/tracker/?func=detail&aid=2945855&group_id=192054&atid=939854 |

| guiott | 0:d177c0087d1f | 27 | while (( remaining_steps == 20 ) || ((fabs(delta_lambda) > 1e-12) && (remaining_steps > 0))) |
| guiott | 0:d177c0087d1f | 28 | |
| guiott | 0:d177c0087d1f | 29 | the original code always returns a zero distance if the arrival point longitude |
| guiott | 0:d177c0087d1f | 30 | is equal or smaller than the starting point one. |
| guiott | 0:d177c0087d1f | 31 | |
| guiott | 0:d177c0087d1f | 32 | The mbed module is interfaced with a Garmin GPS sensor (used in standard mode) |
| guiott | 0:d177c0087d1f | 33 | with an external antenna, a 20x4 LCD text display and a 5 keys keypad. |
| guiott | 0:d177c0087d1f | 34 | A curiosity: |
| guiott | 0:d177c0087d1f | 35 | All the hardware components of the test set are mounted on the top of a wooden |
| guiott | 0:d177c0087d1f | 36 | box, looking like a kind of a steampunk navigator. When my daughter looked at |
| guiott | 0:d177c0087d1f | 37 | the box she said: "it looks alike the navigator of the da Vinci car". |
| guiott | 0:d177c0087d1f | 38 | This is the reason why the name of this project is "Leonardo". |
