12 Common Mining Processes Prospect Survey Plan Drill, Blast
Shovel Haul, Dump Extract/ Process Product = Copper, Gold,
Diamonds, Etc. All these steps need to know where you are and where
the ore is located.
Slide 13
13 What are Terralites? Terralites are a Ground-based signal
generators. They are used in conjunction with GPS and Glonass
satellite constellations They are used for 24/7 Real-time Augmented
positioning coverage.
Slide 14
What features do they have? A new positioning signal Broadcast
by each Terralite XPS Transmit Station Single channel XPS
code/carrier Does not consume GPS or Glonass bandwidth Typically
requires governmental approval for site use Not susceptible to
typical interference of license-free bands (e.g. 900MHz, 2.4GHz)
Self surveying
Slide 15
What do they do? Terralites transmit an XPS signal. XPS
(Extended Positioning Signal) The XPS signal is a licenced
frequency A licence frequency means that you will not have signal
interference The signal is in the X band range
Slide 16
Why do we need them?

Autonomous Solution Errors due to the Ionosphere, Troposphere,
Satellite Clocks and Orbit information reduce the position
accuracy. A non corrected position is an Autonomous position. An
autonomous position would have an accuracy greater than 4m.
Slide 32
RTK Correction Real Time Kinematic
Slide 33
RTK Delivery Reliable RTK delivery is required or the receivers
will not be in a high precision mode. RTK delivery is provided by
mine duty wireless IP radios. Expected typical RTK throughput is
greater than 99%.

Site Survey In a Site Survey analysis, the mine company
provides to Trimble: A three-dimensional mine map for every stage
of the mine plan to be analysed. A list of areas in the mine where
equipment will typically be working.
Slide 38
Site Survey Field Work Obstruction survey Locations recorded
with 360 vertical angle observations of obstructions. Note dumps,
infrastructure and topography which may not be on the 3D models
provided by site. Locations, Field of view, Access, Power, Safety
concerns and open Sky for Terralites Locations, Access, Power,
Safety and open sky for Reference stations Machine mountings and
cable lengths Wireless network coverage
Slide 39
Site Report Trimble conducts an analysis and provides a report
to the mine, which includes: The expected availability of a
positioning sensor, when only GNSS satellites are used for the
solution, for each stage of the mine plan (and thereby showing
potential room for improvement by installation of Terralite
infrastructure). The type of Terralite constellation that best
meets the needs of the mine at each stage. For example, a Standard
constellation or Network constellation. The locations of the
Terralite transmitters and Reference Stations for each stage of the
mine plan.
Slide 40
Site Analysis Using the site pit shells we can simulate the
satellites visible from all points within your mine using the mine
terrain as an obscurity mask. We use a grid to determine the points
in the mine. The grid spacing can be anything of our choosing but
we would tend to use around a 20m spacing depending on the area to
cover. For every point in that grid the simulation records the GPS
and Glonass satellite data including all DOP values and records it
into a database, observations taken every minute for a 24 hour
period. Thus each point will have 1440 entries. Multiply that by
the number of points and you have a very extensive site coverage
analysis. The information can then be displayed visually by showing
you a coloured mine plan indicating where the areas of poor
coverage are. We can also display duration information for each
point. A report is provided explaining the various DOPS and
coverage the mine has. We can also tailor a Terralite solution to
provide up to 100% coverage.
