Detailed Description

A subsystem for the Ublox ZOEM8Q GNSS module.

This Subsystem handles the setup and reading of data from the ZOEM8Q GNSS module.

This Subsystem emits GNSSDataMsg messages to its subscribers.

Constructor & Destructor Documentation

◆ Sensor_ZOEM8Q()

Sensor_ZOEM8Q::Sensor_ZOEM8Q	(	uint8_t	id,
		TwoWire &	pipe,
		uint32_t	freq
	)

inline

Construct a new Sensor_ZOEM8Q object.

Parameters

id	The ID of the Subsystem
pipe	The I2C bus to use
freq	The frequency to use for the I2C bus

Member Function Documentation

◆ loop()

int8_t Sensor_ZOEM8Q::loop ( )

overridevirtual

1: no fix, 2: 2D fix, 3: 3D fix 4: GNSS + dead reckoning combined, 5: time only fix

Implements Subsystem.

◆ performOnlineAssist()

int8_t Sensor_ZOEM8Q::performOnlineAssist ( )

------— AIDING SEQUENCE------— Datasheet section 13.5 (pg. 34) — Note that we are altering the AID_INI part of the message and leaving the rest as is. — • Power-up the GPS receiver • Send UBX-AID-INI (time, clock and position) message. • Send UBX-AID-EPH (ephemeris) message. • Apply optional hardware time synchronization pulse within 0.5 s after (or before, depending on the configuration in UBX-AID-INI) sending the UBX-AID-INI message if hardware time synchronization is required. When sending the message before applying the pulse, make sure to allow the GPS receiver to parse and process the aiding message. The time for parsing depends on the baud rate. The processing time is 100 ms maximum. • Send optional UBX-AID-HUI (health, UTC and ionosphere parameters) message. • Send optional UBX-AID-ALM (almanac) message.

this file ("mgaonline.ubx") should be loaded into the onboard SD card the file should be obtained from the ublocks server the generator token for that can be obtained from thingstream from ublocks See https://developer.thingstream.io/guides/location-services/assistnow-getting-started-guide for more details

Note: The file needs to be called "mgaonline.ubx" and placed in the root of the SD card

◆ setup()

int8_t Sensor_ZOEM8Q::setup ( )
