Fast gps and wireless ?

I want to build a datalogger for a racing car.

I want to record

gps position
Rpm
G force
Lap time
Road speed

Everytime the car passes the start finish line i want the data transmitted

Ideally the data will be transmitted live with a longrange wifi connection

What type of gps sender needs to be used ? Some of them are very cheap. I guess they have a slow update frequency ?

Can you reveal what distrance a 'longrange wifi connection' is and the location\terrain ?

I suspect the forum does not know ....................

Also, what update frequency would be acceptable. Numbers, please.

Ideally the data will be transmitted live with a longrange wifi connection

it is my belief that wifi would be less than ideal. if the connection is not continuous you will need to reestablish it every lap. this will probably take so much time you don't have time to transmit the data

I would start with HC-12 modules with a 15 dbi collinear antenna at the receiving end. that is the highest gain omnidirectional antenna available. anybody claiming more than 15 dbi for a collinear is not a credible person.

Range is typically less than 1km
Terrain is flat
Gps updates of 10hz should be ok

I have a lora wifi / usb interface that might be ok for this application

LoRa and wifi ? LoRa is not wifi as most people would understand.

So you want to use LoRa or WiFi ?

It can use lora or wifi, what ever works best

I have this type

You first post was asking which were the best types to use ?

I for one do not have a clue what type those modules are you have now apparently decided to use are.

No the question was about which type of gps device to use :smiley:

"What type of gps sender needs to be used ? Some of them are very cheap. I guess they have a slow update frequency ?"

this is the transceiver i have

what is the deal with the arduino compatible gps devices ?

are they able to update at a decent accuracy and frequency ?

3DR Radio Telemetry - Geeetech Wiki

The 3DR is neither LoRa or WiFi.

Deal?

Depends. What are you willing to pay?

How does it work ? Is it a radio serial port ?

Have you tried any of the gps devices ? Did you get good results ?

Yes, and yes. On the other hand, I have realistic expectations for a GPS. I do not expect centimeter resolution of the position of a supersonic aircraft.

Which one(s) did you use ?

What was the update frequency ?

that response must requires posting this link:

Ground speed check - mines bigger than yours: Yeah, right, buddy

Haha :slight_smile:
