1975

Navigating the future of avionics since 1975.

The story began with the first prototypes of an electronic variometer. Fifty years later, it continues in every cockpit we equip.

THE BRAND

It started in a garage in Celje.

In 1975, Črtomir Rojnik — a pilot and engineer — began crafting the first electric variometers in his home garage. That work made LX navigation a pioneer of glider navigation, and for fifty years we have pushed the boundaries of aviation technology with instruments that raise flight performance and safety.

Today the range spans glider computers and variometers, solutions for powered aviation, and anti-collision systems. Whether you are a seasoned pilot or just starting your gliding journey, LX navigation has the tools to take your flying to new heights.

1975
1975 — 1985

First prototypes of the electronic variometer.

1975
The first prototypes

A technically complex instrument for a simple job — showing rate of climb and descent in a sailplane. It became the keystone of now-leading air navigation systems worldwide.

1978 — 1979
EV 80

The first successful variometer is born: a pneumatic variometer with mechanical indicator, electro-mechanical MacCready and Speed command. Produced in low quantities and flown in Slovenian aeroclubs — the fact that some of them still work speaks for itself.

EV 80 variometer
1980 — 1982
EV 82 → LX 100 / LX 1000

Constant improvements led to the EV 82, then the big breakthrough: an LCD screen with variometer, integrator, Speed command and OAT. The LX 100 club variometer with its 80 mm cutout instantly became a classic that is still flown today; the LX 60 packed the same functions into a smaller housing.

1985
LX 2000

A highly capable instrument with the power to calculate final glide and wind, with 8 different flight modes — all processed by a micro-controller and shown on one of the first matrix numeric displays of its time.

1992
1986 — 1996

GPS enters the cockpit.

1986
Into cockpits worldwide

Development continues as the sales numbers grow — more and more worldwide customers, with a presence in basically every glider cockpit.

1992
LX 4000

A major milestone and instant success — our first device with an integrated GPS system and an airport & turnpoint database, designed as a merge of three units: control unit, glide computer and vario integrator, with a big custom-designed Iskra display.

1993
LX 400 · LX 3000

A 57 mm navigation instrument for ultralights with integrated GPS receiver, database and matrix display — about 1000 sold. The LX 3000 brought micro-controller power to an older legend, the LX 1000.

1994
LX 20

A legend is born: an IGC-approved logger with all the functions of modern navigation of that era. Known for its unique design and big graphic display, it became a classic in every glider cockpit — sold in thousands, still flying around the globe.

1995
LX 5000

Extended database capacity, airspace, IGC-approved flight recorder and LCD vario indicator — made in 11 improving versions: 1–7 with a 64 × 128 display, 8–9 with co-processors, 10–11 with a high-resolution 240 × 320 screen.

1996
LX 160 · LX 1600

A great, affordable vario-navigation system, popular for its dimensions — just two 57 mm cutouts for control unit and switch indicator. The LX 1600 with its dislocated GPS receiver saved even more space as a single 57 mm instrument.

LX 160 vario-navigation system
1999
1997 — 2007

Colibri, the BUS, and Flarm.

1997 — 1998
LX Remote · DX 50

A wooden steering unit with one main and eight additional buttons, its classic wood-and-leather design still found in many sailplanes — and the DX 50, a compact LX 5000 with plug-ins, display, LCD variometer and IGC logger that competition pilots could take out and hand to the judge.

1999
Colibri

The smallest IGC-approved flight recorder of its time, with optional keyboard and alpha-numeric display. Ahead of its era, sold in thousands — many still in use.

2000
LX 20-2000

The GPS logger successor to the LX 20 — identical in usage and functions, but with a new housing, keyboard and different connectors, and support for various navigational applications.

2003
LX 7000

The first vario-navigation system with variometer and computer as separate units connected via BUS — airspace, database and tasks shown perfectly clearly on a high-resolution display.

2005
LX 7007 + Flarm

Embedded computing power and, for the first time ever, our own licensed anti-collision system: Flarm. The FLARM RedBox released the same year was an instant hit; Mini Box, Flarm mobile and the LX LED display followed — over 10,000 units produced and flying worldwide.

LX 7007 pro IGC
2012
2007 — 2017

First color system — and Zeus.

2008
LX 8000

The first color-display, Linux-operated GPS vario-navigation system developed and produced at LX navigation.

2010
LX Mini Map

A high-brightness handheld in the age of unreadable PDAs — a must-have for glider pilots. The same year, built on the same platform, Mini Map pro was released for panel installation, controlled by rotary knobs and 6 buttons.

2011
LX 7007 C · Colibri II

New micro-controller technology and a color display made the LX 7007 C a popular choice — everything you need in an 80 mm instrument. And Colibri II, the second Colibri, won again: a simple variometer with IGC logger in a handy housing, sold in thousands.

2012
Zeus

35 years of experience placed together in one ground-up instrument: all-new technology and coding, CAN bus connectivity, a new interface, and marked push-rotary buttons. Produced in four display sizes — 4.3″, 5.5″, 7.0″ and 8.0″ — with an 80 mm (2.8″) version a year later. An instant classic.

2015
Eos · Helios · LX Joy

The world's first standalone IGC-approved flight recorder with variometer: Eos, with integrated GPS, backup battery, task and turnpoint navigation, G sensor, Flarm indicator, AHRS, Bluetooth and logbook. Beside it the club vario Helios with FLARM radar and warnings — and LX Joy, the hand-stitched leather remote.

2017
The smart platform

Development continues with smart-platform devices like LX Era — WiFi and Bluetooth connectivity as the basis for cloud solutions, and a new ideology for future development.

2025
2017 — TODAY

NAVIA · 50 years

Half a century after the first prototype, Navia arrives — voice, spatial audio, PoE and the cloud. A new beginning.

Navia Display 12, 7 and 4
A RECORD OF FIRSTS

Someone has to be first.

Fifty years of putting the technology in the cockpit before anyone else did — each one a product you can buy, not a claim about ourselves. Every one of them exists to do the same two things: make the flight safer, and give the pilot less to do.

  1. 2025

    The first AI voice assistant in avionics

    Navia Core Pro takes spoken commands — set a radio frequency, change a task, ask for the next airfield — so the workload of a menu tree never reaches the pilot in the first place.

  2. 2025

    The only cockpit device with a built-in worldwide eSIM

    Navia Core Pro carries its own global SIM, so weather, airspace and airfield information stay current in the air, across borders, with no phone, no hotspot and nothing to plug in.

  3. 2025

    The largest and highest-resolution displays in gliding

    Navia Display 12 is 11.6 inches of Full HD at 1600 nits and 190 PPI — anti-reflective, anti-glare and anti-fingerprint, and still readable with the sun behind you.

  4. 2025

    The only heated control stick in aviation

    Navia Grip is hand-stitched leather over a heated core, with vibration alerts and the voice assistant under your thumb. Cold hands are a workload problem, and this is the only grip that solves it.

  5. 2024

    The world's first digital certified airspeed indicator and altimeter in one instrument for gliding

    iris All-in-One replaces two certified analogue instruments with one EASA-approved digital unit — with its own backup battery, so it keeps indicating when the aircraft electrics do not.

  6. 2021

    The world's first touchscreen IGC flight recorder

    Colibri X put a transflective capacitive touchscreen on an IGC-approved recorder: task navigation you operate the way you operate everything else, and logs an Official Observer accepts.

  7. 2015

    The world's first standalone IGC flight recorder with a variometer

    Eos combined an approved logger, GPS, backup battery, task navigation, G sensor, AHRS and Bluetooth in one instrument — the pattern the whole category followed afterwards.

  8. 2005

    The first flight computer with FLARM built in

    LX 7007 pro IGC embedded a licensed FLARM collision-avoidance system inside the navigation computer instead of beside it. LX navigation has been a FLARM partner since day one and has shipped over 10,000 FLARM units.

  9. 1994

    A generation of gliders learned to navigate on our instruments

    The LX 20 and LX 5000 defined what a glider flight computer does and how it is operated — the interface conventions still in use across the industry today.

  10. OEM

    Constant-speed propeller governors for Woodcomp and DUC Hélice

    The constant speed 57 controller is built by LX navigation and supplied to propeller manufacturers as the governor for their own systems.

Not to be confused with LXNAV, a separate company established later. LX navigation is the original firm, founded in Celje in 1975.

BRAND VISUAL IDENTITY

Evolution of the logo.

It started as simple text. Then the symbol appeared — an abstract bird, a glider in flight. It disappeared for years, and returned in 2020 as the stylised bird: flying, progress, power.
