Q: What are the minimum versions of Windows, Android, iOS, and macOS operating systems?

💻 Desktop: macOS : Version 13 (macOS Ventura), released on October 24, 2022, and all later versions. (x86_64, x86_64h, and arm64). Windows : Version 10 (build 1809 - 10.0.17763) or later, Windows 11 - x86_64 and ARM64, released in October 2018. 📱 Mobile: Android : Version 9 (API 28) to 15 (API 35) - arm64-v8a, x86_64, x86, and armeabi-v7a. Android 9 was released in August 2018. iOS : Version 16 or later (including iOS 18) - armv8, arm64. iOS 16 was released in September 2022. ⚠️ Important: These operating system versions are prerequisites for running NavimetriX, as they define compatibility with our development framework. However, they do not guarantee that the application will be fully compatible with your device. Other factors such as insufficient RAM or a low-performance graphics processor may also affect performance and compatibility.

Question 1

How to display AIS targets over Internet?

Francis · Accepted Answer

AIS targets over Internet come from the global AISHub network, to which NavimetriX is affiliated.

The coverage area is available on an interactive map.

The use and handling of AIS targets over Internet is exactly the same as for AIS targets received on board using an AIS receiver that transmits NMEA data to the application. For more details, see:

How to display AIS targets? in this FAQ.

Open the Settings panel (gear button at the top right)

Select the AIS option
Enable AIS over Internet

AIS targets via the Internet are represented **in blue**

Cautions:

AIS targets over Internet should be considered for informational purposes only. Time delays due to Internet transfer speeds make them unsuitable for navigational safety, whereas reception on board by a dedicated receiver is at VHF frequency in real time.

They are therefore represented by blue icons to differentiate them from green AIS targets icons received directly.

Question 3

Which NMEA0183 XDR sensors can I use?

Henri · Accepted Answer

FAQ - NMEA0183 XDR Sentence (Transducers)

What is the XDR sentence?

The XDR (Transducer Measurement) sentence is a generic NMEA0183 sentence used to transmit measurements from various types of sensors (transducers). It allows multiple measurements to be grouped into a single sentence.

What is the general format of the XDR sentence?

$xxXDR,a,x.x,u,n,a,x.x,u,n,...*hh

Where for each transducer group:

a: Transducer type (one letter)
x.x: Measured value
u: Unit of measurement (one letter)
n: Transducer name (character string)

The checksum (*hh) is mandatory.

Which transducers are supported by NavimetriX?

1. Heel/Pitch

Field	Value
Type	`A` (Angular)
Unit	`D` (Degrees)
Name	`PTCH`

Example:

$IIXDR,A,5.2,D,PTCH*XX

This indicates a pitch angle of 5.2°.

2. Roll

Field	Value
Type	`A` (Angular)
Unit	`D` (Degrees)
Name	`ROLL`

Example:

$IIXDR,A,-1.1,D,ROLL*XX

This indicates a roll angle of -1.1°.

Combined example (Roll + Pitch):

$IIXDR,A,-1.1,D,ROLL,A,5.0,D,PTCH*74

3. Water Temperature

Field	Value
Type	`C` (Temperature)
Unit	`C` (Celsius), `F` (Fahrenheit), or `K` (Kelvin)
Name	Must contain `water` (e.g., WATERTEMP, WaterTemp, water)

Examples:

$IIXDR,C,18.5,C,WATERTEMP*XX
  $IIXDR,C,65.3,F,WaterTemp*XX
  $IIXDR,C,291.65,K,water*XX

4. Air Temperature

Field	Value
Type	`C` (Temperature)
Unit	`C` (Celsius), `F` (Fahrenheit), or `K` (Kelvin)
Name	Must contain `air` (e.g., AIRTEMP, AirTemp, air)

Examples:

$IIXDR,C,22.0,C,AIRTEMP*XX
  $IIXDR,C,71.6,F,AirTemp*XX

Combined example (Water + Air):

$IIXDR,C,18.1,C,WATERTEMP,C,22.0,C,AIRTEMP*49

5. Barometric Pressure

Field	Value
Type	`P` (Pressure)
Unit	`B` (Bars)
Name	Must contain `baro` (e.g., BARO, Barometer, baro)

Note: The value must be expressed in Bars (1 bar = 1000 hPa). NavimetriX automatically converts it to hPa.

Example:

$IIXDR,P,1.013,B,BARO*XX

This indicates a pressure of 1013 hPa.

How do I combine multiple measurements in a single sentence?

Transducer groups can be chained in the same XDR sentence (up to 10 transducers per sentence):

$IIXDR,A,-2.5,D,ROLL,A,3.1,D,PTCH,C,18.5,C,WATERTEMP,C,21.0,C,AIRTEMP,P,1.015,B,BARO*XX

Is the transducer name case-sensitive?

No. Transducer name recognition is not case-sensitive for temperatures and pressure:

WATERTEMP, WaterTemp, watertemp → all recognized
AIRTEMP, AirTemp, airtemp → all recognized
BARO, Barometer, baro → all recognized

Exception: For roll and pitch, the names must be exactly ROLL and PTCH.

Which talker prefix should I use?

NavimetriX accepts all standard talker prefixes (II, GP, HC, etc.). The examples above use $II (Integrated Instrumentation), but $GP, $HC, or others are equally valid.

Summary of accepted formats

Measurement	Type	Unit	Transducer Name
Pitch	A	D	`PTCH`
Roll	A	D	`ROLL`
Water temperature	C	C, F, or K	contains `water`
Air temperature	C	C, F, or K	contains `air`
Barometric pressure	P	B	contains `baro`
