Assuming we're talking just about Android platform only, as @Joerg rightly says, you can use cordova.plugins.diagnostic to check if GPS is enabled using isGpsLocationEnabled():

cordova.plugins.diagnostic.isGpsLocationEnabled(function(enabled){
    console.log("GPS location is " + (enabled ? "enabled" : "disabled"));
}, function(error){
    console.error("The following error occurred: "+error);
});    

If the result is that GPS is switched off, you can either switch the user to the location settings page to manually enable GPS:

cordova.plugins.diagnostic.switchToLocationSettings();

Or, in addition, you could use cordova-plugin-request-location-accuracy to request high accuracy location mode (i.e. GPS) directly from within the app. This will show a native confirm dialog and if user agrees, GPS will be enabled automatically:

function onRequestSuccess(success){
    console.log("Successfully requested accuracy: "+success.message);
}

function onRequestFailure(error){
    console.error("Accuracy request failed: error code="+error.code+"; error message="+error.message);
    if(error.code !== cordova.plugins.locationAccuracy.ERROR_USER_DISAGREED){
        if(window.confirm("Failed to automatically set Location Mode to 'High Accuracy'. Would you like to switch to the Location Settings page and do this manually?")){
            cordova.plugins.diagnostic.switchToLocationSettings();
        }
    }
}

cordova.plugins.locationAccuracy.request(onRequestSuccess, onRequestFailure, cordova.plugins.locationAccuracy.REQUEST_PRIORITY_HIGH_ACCURACY);
