## Constructor & Destructor Documentation

## ◆ ~gps_iface()

virtual uhd::features::gps_iface::~gps_iface | ( |  | ) |

## Member Function Documentation

## ◆ get_feature_id()

discoverable_feature::feature_id_t uhd::features::gps_iface::get_feature_id | ( |  | ) |
| inline static

## ◆ get_feature_name()

std::string uhd::features::gps_iface::get_feature_name | ( |  | ) | const
| inline virtual

Returns a human-readable string name of this feature.

Implements uhd::features::discoverable_feature.

## ◆ get_sensor()

virtual uhd::sensor_value_t uhd::features::gps_iface::get_sensor | ( | const std::string & | key | ) |
| pure virtual

Retrieve the sensor value by name

This will return the same sensors as the motherboard sensors, but only the ones that are relevant to the GPS.

## ◆ get_sensors()

virtual std::vector< std::string > uhd::features::gps_iface::get_sensors | ( | void |  | ) |
| pure virtual

Retrieve the list of sensors this GPS object provides

## ◆ send_cmd()

virtual std::string uhd::features::gps_iface::send_cmd | ( | const std::string & | cmd | ) |
| pure virtual

Submit an arbitrary command to the GPS device.

Using this can cause the GPS to enter an unknown state, so use with caution. It is up to the user to identify correct and valid commands.

If the command is terminated with a '?' symbol, the GPS device will assume that the user is requesting information and will return the response. If the command is not terminated with a '?', this function will return an empty string.

Example:

std::string response = gps_ifc->send_cmd("SYNC:FEE?");
std::cout << "Frequency Error Estimate: " << response << std::endl;

Returns
  The response from the GPS device, or an empty string.
