NANO GPS Click

How does it work?

Nano GPS Click is based on the Nano Hornet ORG1411, a complete SiP GPS Patch-on-Top (PoT) module from OriginGPS. The GPS module supports the L1 band only at 1575.42MHz for GPS, with 48 channels. The module is an ultra-low tracking power consumption device with a high sensitivity of -163dBm while tracking and -162dBm in reacquisition mode with less than 1 second of reacquisition time. The larger number of visible satellites increases horizontal positioning accuracy (<2.5m CEP) and decreases acquisition time (<1s TTFF with a hot start and <32 with a warm start). Nano GPS Click supports an active jammer detector/remover and better positioning under signal conditions with onboard dual-stage LNA for better sensitivity. It also features OriginGPS Noise Free Zone System (NFZ™) technology, Autonomous and Predictive A-GPS, Ephemeris Push, Almanac Based Positioning, and more.

As the module works on 1.8V, this Click board™ uses four voltage translators, the 74LVC1T45 from Diodes Incorporated, for all data lines connected with the host MCU, except for the RST signal used for resetting the device. The ORG1411 uses the UART interface with commonly used UART RX and TX pins as its default communication protocol to transmit and exchange data for communication with the host MCU. The Power State Control pin PWR switches the module between different power states, such as Hibernate state, STP, PTF, and Full Power state. The WUP pin is output from the module and indicates its power state, while the PPS LED provides a visual pulse signal for timing purposes.

This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the PWR SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.

Software Support

We provide a library for the Nano GPS Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Nano GPS Click driver.

Key functions

• Generic parser function.

• Generic read function.

• Wake-up module.

Example Description

This example reads and processes data from Nano GPS clicks.

 void application_task ( void ) 
 { 
     nanogps_process(  ); 
     parser_application( current_parser_buf ); 
 }

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.Nanogps

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.

mikroSDK

This Click board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
