1 Introduction

ltesat is a companion software of Amarisoft eNB/gNB for any NTN scenario and features two main functions:

1.1 Toolbox mode

It can be used ’offline’ like a toolbox to replay or plan any satellite orbit. It accepts various inputs for satellite description which are compatible with eNB/gNB NTN configuration and can output the satellite trajectory with several formats: azimuth/elevation from a given ground position, groundtrack or ECEF coordinates.

It can also be used as a pass predictor over a given ground position.

It can also export a given satellite description to another format, e.g to generate a TLE file.

1.2 Mission control mode

Secondly, it can be used as a ’mission control’ software to control several Amarisoft eNB/gNB working with a worldwide LEO constellation. The configuration file contains a mapping between ground cells and Amarisoft eNB/gNBs with an NTN configuration, along with the definition of a satellite constellation. ltesat will configure in realtime the eNB/gNBs to select the serving satellites for its NTN cells, in order to allow a continuous coverage in time.

ltesat offers the same comprehensive logging mechanism as other Amarisoft products and smoothly interfaces with Amarisoft GUI.

2 Requirements

2.1 Hardware requirements

ltesat is not a performance-intensive executable and can run on any machine.

2.2 Software requirements

A 64 bit Linux distribution. Fedora 42 is the officially supported distribution.
The following distributions are known as compatible:
- Fedora 22 to 42
- Cent OS 7
- Ubuntu 14 to 24
Your system requires at least GLIBC 2.17.

3 Installation

ltesat can be run directly from the directory where it was unpacked.

3.1 Linux setup

ltesat does not need external packages.

3.2 Licensing

ltesat needs a valid Amarisoft license with the NTN option to run.

3.3 Initial testing

To display the satellite groundtrack:
```
./ltesat sat-groundtrack.cfg
```
To act as a mission control:
```
./ltesat -m sat-mc.cfg
```
In mission control mode, the ltesat runs until it receives a Ctrl+C termination command.

4 Configuration reference

4.1 Configuration file syntax

The main configuration file uses a syntax very similar to the Javascript Object Notation (JSON) with few extensions.

Supported types:
- - Numbers (64 bit floating point). Notation: 13.4
- - Complex numbers. Notation: 1.2+3*I
- - Strings. Notation: "string"
- - Booleans. Notation: true or false.
- - Objects. Notation: { field1: value1, field2: value2, .... }
- - Arrays. Notation: [ value1, value2, .... ]
The basic operations +, -, * and / are supported with numbers and complex numbers. + also concatenates strings. The operators !, ||, &&, ==, !=, <, <=, >=, > are supported too.
The numbers 0 and 1 are accepted as synonyms for the boolean values false and true.
{} at top level are optional.
" for property names are optional, unless the name starts with a number.
Properties can be duplicated.
If properties are duplicated, they will be merged following JSON merge rules with overriding occuring in reading direction (last overrides previous).
Ex:
```
{
    value: "foo",
    value: "bar",
    sub: {
        value: "foo"
    },
    sub: {
        value: "bar"
    }
}
```
Will be equivalent to:
```
{
    value: "bar",
    sub: {
        value: "bar"
    }
}
```
Files can be included using include keyword (must not be quoted) followed by a string (without :) representing the file to include (path is relative to current file) and terminating by a comma.
Arrays can’t be included.
Merge will be done as for duplicate properties.
If file1.cfg is:
```
    value: "foo",
    include "file2.cfg",
    foo: "foo"
```
And file2.cfg is:
```
    value: "bar",
    foo: "bar"
```
Final config will be:
```
{
    value: "bar",
    foo: "foo"
}
```
A C like preprocessor is supported. The following preprocessor commands are available:

#define var expr

Define a new variable with value expr. expr must be a valid JSON expression. Note that unlike the standard C preprocessor, expr is evaluated by the preprocessor.

#undef var

Undefine the variable var.

#include expr

Include the file whose filename is the evaluation of the string expression expr.

#if expr

Consider the following text if expr is true.

#else

Alternative of #if block.

#elif

Composition of #else and #if.

#endif

End of #if block.

#ifdef var

Shortcut for #if defined(var)

#ifndef var

Shortcut for #if !defined(var)

In the JSON source, every occurrence of a defined preprocessor variable is replaced by its value.
Backquote strings: JSON expression can be inserted in backquote delimited strings with the ${expr} syntax. Example: `abc${1+2}d` is evaluated as the string "abc3d". Preprocessor variables can be used inside the expression. Backquote strings may span several lines.

4.1.1 JSON merge rules

Merge overriding direction depends on context, i.e source may override destination or the opposite.
JSON merge is recursive for Objects and Arrays.

Example, merging

{
    foo: { value: "bar" },
    same: "one",
    one: 1
}

with

{
    foo: { value: "none", second: true },
    same: "two",
    two: 1
}

Will become:

{
    foo: { value: "bar", second: true },
    same: "one",
    one: 1
    two: 1
}

assuming first object overrides second one.

In case of Array merging, the final array length will be the maximum length of all merged arrays.
For each element of the final array, merge will be done considering defined elements only.
Ex:

{
    array: [0, 1, 2, { foo: "bar" } ],
    array: [3, 4],
    array: [5, 6, 7, { bar: "foo" }, 8 ]
}

Will be merged to:

{
    array: [5, 6, 7, { foo: "bar", bar: "foo" }, 8 ],
}

4.3 Single satellite descriptor object

This object is placed either as an element of a constellation object of array type (See constellation) or at the top level of the configuration file (for a single satellite configuration).
Its configuration is compatible with the ntn object in Amarisoft eNB/gNB configurations.
It contains the following parameters:

The file shall contain only the two lines of data and optionally a title line.
When the parameter is present, ephemeris is ignored.

default_ephemeris

Optional enumeration: geo, meo, leo. Default is geo.
If ephemeris is absent, a default satellite ephemeris is generated so that the satellite is overhead the eNB ground position at the time specified by start_time. The GEO and MEO satellite will be placed on the equatorial plane (zero inclination) at the longitude of the eNB ground position.
The LEO satellite will be initially placed at the zenith of the eNB position.

default_altitude

Optional float, range 200e3 to 36000e3. If default_ephemeris is used and set to meo or leo, this parameter (in meters) allows to override the altitude of the chosen orbit.
The parameter is ignored otherwise. The default values are 550e3 for leo and 8063e3 for meo.

default_elevation_offset

Optional float, range -90 to 90, default = 0. If default_ephemeris is used and set to leo, this parameter (in degrees) allows to adjust the initial elevation of the satellite compared to the zenith position.
The parameter is ignored otherwise. Negative values will place the satellite before its zenith pass and positive values after the zenith.

ephemeris

Optional object to configure satellite ephemeris in the form of orbital parameters.
The ephemeris configuration is understood in a fixed ECI reference frame aligned with the J2000 vernal equinox, like a TLE configuration. If absent and if tle_filename and sv_filename are also absent, a default ephemeris is generated.

5.1.3 Export

For testing purpose, it could be useful to generate a ’virtual TLE’ that simulates a satellite passing overhead a given location at a given time. Here is an example with the default_ephemeris and export_type parameter, stored in sat-export.cfg:

/* ltesat configuration file version ##VERSION##
 * Copyright (C) 2024-2025 Amarisoft
 */

{
    output_mode: "az_el",
    n_steps: 10,
    step_ms: 30000,
    start_time: "2024-03-15T14:30:00",

    ground_position: {
        latitude: 48.8538,
        longitude: 2.3475
    },

    default_ephemeris: "leo",
    default_altitude: 700e3,
    default_elevation_offset: -60,

    export_type: "tle",
    export_time: "2024-03-15T00:00:00.000",
    export_filename: "pass_14h30.tle"
}

And the resulting TLE pass_14h30.tle:

1 99999U 24999A   24075.00000000 -.00000000  00000-0  00000-0 0    11
